Affective Computing represents a challenging research field at the intersection of Artificial Intelligence, Neuroscience and Psychology. The main objective of the research group is the analysis and detection of human emotions, of affective and cognitive states, as well as the human-machine interaction. Such areas are investigated through the application of advanced Artificial Intelligence techniques, that allow to provide efficient solutions in several application areas, including social robotics, health support, education and virtual and augmented reality, with a particular focus on applications that support wellness and quality of life.
The research group has always paid great attention to the ethical and social implications of Affective Computing technologies, promoting the ethical responsibility of the developers and researchers involved in the various projects. Furthermore, the group encourages interdisciplinary collaborations with experts from different research areas, in order to promote continuous cross-fertilization and an ever-increasing understanding of the role of emotions and affective states in human communication with technologies.

The research group deals with the study of methods of Real Analysis and Approximation Theory aimed at signals and images reconstruction and processing. It is now evident, in fact, the strong need, in almost all the applied sectors in the medical and industrial fields, for the mathematical modeling of processes and their consequent algorithmic application. Science, even experimental science, needs very refined and rigorous scientific tools that require mathematical skills aimed at the applications. In particular, the theoretical models developed within this research topic, which mainly concern with the approximation properties of families of operators in various functional spaces, are implemented to provide mathematical and numerical algorithms for digital image processing aimed at the solution of concrete problems in particular in medical and engineering fields. The group refers to the "Imaging and Computer Vision (ICV)" laboratory, at the Department of Mathematics and Computer Science, created also with the purpose of developing research in this area. The same group of researchers is among the founding members of the Working Group of the Unione Matematica Italiana called "Theory of Approximation and Applications" which brings together Italian researchers who are experts in these research topics. Many of the researchers in this group are lecturers in the Laurea Magistrale in Mathematics for Biomedical and Industrial Applications. In addition to the various international scientific collaborations, the group has a strong interdisciplinary character and has developed strong collaborations and research in the medical field (mathematical models and algorithms for the study of aneurysmatic pathologies, retinal pathologies, brain pathologies for the search of biomarkers for Alzheimer's disease) and in the engineering field (mathematical models for the seismic vulnerability of buildings, for the study of thermal bridges and acoustic bridges), making use of an intense collaboration with the Departments of Civil and Environmental Engineering (DICA), of Engineering (DI) and of Medicine and Surgery of the University of Perugia, and with the Radiology and Medical Physics section of the Santa Maria della Misericordia Hospital in Perugia. The mentioned collaborations have led to the production of scientific publications in ISI journals, as well as very intense project collaborations. On these studies members of the research group have two patents. There are also active collaborations with local and non-local companies. In many of these areas, research is still being developed: new areas of application are opening up (for example the study of thrombotic pathologies in cancer patients) and others will open in the future. A line of research in continuous ferment, where both theoretical and applied research will surely destined to spark a deep development and interest within the international scientific community.

Poisson structures are geometric structures that play a decisive role in explaining the relationships between quantum mechanics and classical Hamiltonian mechanics and are the basis for some of the most popular approaches to quantization procedures such as "deformation quantization" and geometric quantization. The study of Poisson manifold quantization using symplectic integration and producing as output the C * -algebra of convolution of a groupoid has opened new study scenarios on the relationships between geometric invariants and quantum properties. In particular, the attempt to understand the functorial properties of this construction naturally leads to consider the notion of differentiable stack and the analysis of homotopy properties, both in the proper sense and in categorial sense of the Poisson invariants.

The core themes of this research field are Galois Geometries, Algebraic Curves in positive characteristic and Combinatorial Graphs. In their study, several tools developed reveal to be particularly performing in the interaction both with classical mathematics (Number Theory, Algebraic Geometry, Group Theory), and with the more recent ones connected with applications to Code Theory and Cryptography, with particular reference to correcting and covering codes, to secret sharing schemes and to functions on highly non-linear finite fields. One of the main objectives is to create infinite new classes of remarkable objects in Galois spaces and / or algebraic curves and / or combinatorial graphs with many automorphisms. There are several reasons that justify this choice. First, this is consistent with the discrete analog of Felix Klein's "Erlangen Program", considered by many to be the starting point of modern geometry: organizing geometric knowledge (in our case combinatorial knowledge) in terms of group theory . Secondly, algebra is able to capture / enlighten structures that would otherwise remain hidden. Finally, combinatorial objects with a high degree of symmetry are particularly relevant in the applied field also because they can be stored more efficiently in terms of memory space. The research carried on by the group is also developing in the direction of cryptography applied to Cloud Encryption. Cloud encryption uses advanced encryption techniques to protect the data that will be used or stored in the cloud. It allows users to conveniently and securely access shared services, so that all data hosted by providers are protected with encryption. The mathematical primitives, more precisely algebraic, used in cloud encryption are intended to encrypt sensitive data without delaying the exchange of information, thus protecting critical data beyond the business IT environment.

Nicla Palladino Emanuela UghiAn interaction model between small amplitude acoustic waves and membrane-type extended reaction surfaces is studied. The specificity of the research is the mutual interaction between the physical-mathematical modeling aspect and the theoretical aspect, in the sense that the analytical results can provide indications on the appropriateness of the model. The problem is also related to hyperbolic evolution models for composite systems. In the field of stationary problems, we study some classes of elliptic-type equations or inequalities associated with problems governed by different non-linear operators of the p-Laplacian type or of the non-homogeneous type such as the (p, q) -Laplacian involving critical non-linearities modeling phenomena of interest in the physical, economic, biological and statistical fields. In particular, the p-Laplacian models both dilating and pseudoplastic non-Newtonian fluids such as paints, blood, asphalt or toothpaste. Finally, in the context of evolutionary problems, Fujita-type theorems are studied for quasilinear inequalities of parabolic type having nonlinearities involving nonlocal terms in the spirit of the Choquard equation that appears in various fields of quantum physics and in the theory of relativity, or non-linearities dependent on the gradient and with degenerate or singular weights that generalize models of population dynamics.

Anna Salvadori Rita CeppitelliThe group deals with the study of mathematical models of phenomena in the physical, biological, economic and techno-food fields through a combination of topological methods and functional analysis tools, as well as multivocal analysis. The mathematical formalization naturally leads to consider both differential and integro-differential equations or inclusions subject to various kinds of initial conditions (such as periodic, antiperiodic, multipoint and mean value problems), to pulses or with the presence of delay. The results obtained, that range from the determination of the existence and uniqueness of solutions, to their stability or continuous dependence, find applications to population dynamics, gas kinetic theory, portfolio theory, sterilization problems, heat treatments, microfiltration and clarification of fluids and study of rain infiltration in the soil.

The focus concerns the study of the computational complexity of optimization problems defined in various contexts, including communications and / or processing networks. The approach is to propose optimal, approximating and heuristic algorithms in various applicative contexts including the need to disseminate and / or retrieve data. Wireless networks, ad hoc networks and social networks are being established and discontinued within a short time in order to take advantage of local and instant information. Examples of such networks may concern the need to retrieve environmental information through networks of sensors, drones, or mobile devices such as robots or more commonly used ones such as laptops, smartphones, smartwatches and tablets. The diffusion of such networks is certainly promoted by technological advancement and by the spread of increasingly performing communication devices. These networks are now also used in agriculture where monitoring based on automatic data collection facilitates the automation of decision-making processes. The research group that deals with these issues also avails itself of the collaboration of various researchers from other Italian and foreign Universities. The Haly-id project is highlighted haly-id.

In this research group we deal with complex systems, that is, systems made up of a large number of elements that show a global behavior that is not easily understood by the rules with which the single entities interact with each other. In particular, we use techniques related to statistical physics and dynamical systems to study the formation of patterns and collective dynamics in reaction-diffusion systems both in continuous space and on a complex network. The applications, which are mainly focused in the biological field, make use of a highly multidisciplinary approach thanks to collaborations with various experimental groups.

Analysis of the contribution of the conditional probability approach consistent with merging techniques and aggregation of different information sources, in line with what has already been introduced in several recent contributions on the so-called Statistical Matching, on Probabilistic Databases and on Fuzzy aggregation operators. Search for areas of application of classification techniques, in particular under partial information, which allow the identification of risk conditions based on techniques of Fuzzy rules or aid to decisions with techniques of Rough Set. The group also studies techniques and results of algebraic geometry for the characterization and analysis of probabilistic models based on partial assignments of coherent conditional probabilities. This approach is based on what has been proposed in the literature for the selection of Bayesian network models, in particular the so-called "naive" ones, represented by varieties of the secants of a Segre variety, extending it to the case of more general models with the presence of logical constraints (structural zeros) and only partial or "extreme" assignments (conditioners of null probability). The translation of these constraints into algebraic-geometric properties could lead to properties and characterizations that have not yet been explored.
