Probability and Mathematical Statistics

The scientific activity in this area has several fruitful connections with analysis and statistics, and various applications in economics, finance, physics, biology and other sciences. The main topics are stochastic evolutions, in particular stochastic differential equations in finite and infinite dimensions and particle systems, and the analysis of variational problems in probability, with applications to mathematical finance. The detailed activity of the group can be found here.

Stochastic evolutions

Existence and regularity of densities for solutions of stochastic differential equations and stochastic PDEs. SDEs with coefficients of low regularity, PDEs with problems of uniqueness and blow-up, and corresponding regularization properties due to the presence of noise. Asymptotical statistical properties for equations from fluid dynamics driven by noise. Interacting particle systems from models in neuronal and cellular biology and in physics.
