Averaging along irregular curves and regularization of ODEs – Remi Catellier (Université de Nice Sophia-Antipolis)

Paths of some stochastic processes such as fractional Brownian Motion have some amazing regularization properties. It is well known that in order to have uniqueness in differential systems such as dy_t = b(y_t) dt, b needs to be quite regular.…

Numerical Analysis Seminar – Tensor Analysis: Spectral Theory and Special Tensors – Liqun Qi (The Hong Kong Polytechnic University, Department of Applied Mathematics)

Eigenvalues for tensors were introduced in 2005. Since then, a rich theory on eigenvalues of tensors and special tensors has been developed. There are two main definitions of eigenvalues of tensors. One definition is based upon homogeneous…

La teoria di Hodge dell’algebra di Hecke e in teoria delle rappresentazioni – Leonardo Patimo (Max Planck Institute for Mathematics, Bonn)

Le congetture di Kazhdan-Lusztig forniscono una formula esplicita per calcolare il carattere delle rappresentazioni con peso più alto di un’algebra di Lie semisemplice complessa. La dimostrazione originale di queste congetture si basa su risultati…
