Anàlisi Complexa

Members: Carme Cascante, Konstantin Dyakonov, Jordi Marzo, Xavier Massaneda, Joaquim Ortega, Jordi Pau, Martí PratsEstudiants de doctorat: Victor de la Torre

Description: At the Complex Analysis group we work with problems of holomorphic functions in one and several complex variables as well as with problems of harmonic analysis, potential theory and operator theory that appear naturally when studying classical function theory problems. Lately, we have started a new line of research around the random point processes that appear when modeling repulsive particles.

Anàlisi Estocàstica

Members: Carme Florit, David Márquez, Carles Rovira.

Description: One of our main fields of research is the study of stochastic differential equations: stability problems, stochastic differential equations, delayed or reflected, driven by fractional noise and a type of delayed stochastic models applied to biological models. The other line of research is devoted to problems of almost certain convergence towards Gaussian processes.

Description: The group develops its research in the field of Quantitative Finance using stochastic analysis techniques (Gaussian processes, Lévy processes, martingale theory, Itô calculus, Malliavin calculus, stochastic differential equations, stochastic partial derivative equations, etc.) and numerical methods (Monte Carlo simulation, Machine learning, Wavelets, etc.). Addresses financial problems using stochastic volatility jump-diffusion models. In particular, problems like pricing and hedging of financial derivatives, market modelling, risk modelling, computation of sensitivities, description of volatility surfaces, and others.

Description: Our research interests focus on the analysis of Partial Derivative Equations (EDPs). We study a wide variety of problems, including: fluid mechanics, elliptic equations, functional and geometric inequalities, or spectral problems, combining techniques of variational analysis, harmonic analysis, geometric theory of measurement.

Description: Our group is aimed to the study of problems in Mathematics within the areas of Linear, Algebraic and Differential Geometry, not only in its theoretical aspects but also focusing in computational features and in applications. To be more precise, we will deal with important questions in diverse topics such as gauge theories, abelian varieties, stability conditions in triangulated categories, Arakelov geometry, reconstruction of shapes starting from clouds of points, elimination theory, lattices in Linear Algebra, and singularities of plane curves.
