- Abstract
  
  In this talk, a nonparametric method for density estimation over complicated spatial domains is presented. The method combines a likelihood approach with a regularization based on a differential operator, and the estimator is proven to be consistent. The discretization of the estimator is based on finite elements, ensuring high computational efficiency and enabling great flexibility. The proposed method efficiently deals with data scattered over two-dimensional regions having complicated shapes, two-dimensional Riemannian manifolds, or planar networks. Moreover, it captures very well complicated signals having multiple modes with different directions and intensities of anisotropy.

- Abstract
  
  Purity in arithmetic algebraic geometry is the phenomenon of certain invariants of algebraic varieties being insensitive to removing closed subvarieties of sufficiently large codimension, the Hartogs' extension principle being the basic example. The most delicate case of such results is in mixed characteristic (0, p), in which a new approach based on perfectoid rings has recently been introduced. I will overview it and discuss the results that it has yielded so far.
