Equilibrium measures on curves
In this talk I will discuss one of the most classical objects of study in potential theory: equilibrium measures for the logarithmic energy. Given a compact set E, the (logarithmic) equilibrium measure on E is …

Analysis in Tatra 2025 (Seminarium wyjazdowe "Analiza w Tatrach 2025")
In Poland there is a long tradition of organizing off-site seminars. The seminar “Functional Analysis in Tatra” is co-organized by Section of Differential Equations and Analysis of the University of Warsaw and Department of Optimization …

Analytical obstructions to the weak approximation of Sobolev mappings into manifolds
In a striking contrast with the situation for classical linear spaces, Sobolev maps with values into a compact manifold N need not be approximable with smooth N-valued maps. While situations where the strong approximation property …

Newton’s problem of least resistance for convex bodies
Isaac Newton (1687) posed the problem of finding the convex axisymmetric body with smallest aerodynamic drag when moving in a highly rarefied medium. Thus, he was looking for the optimal curve which is the generatrix …

On Polyconvexity and Almgren Uniform Ellipticity With Respect to Polyhedral Test Pairs
The ellipticity of an anisotropic energy functional is a property that ensures a flat k-cube is the unique minimizer of the functional among all competitors with the same (k-1)-dimensional boundary as the cube. There is …

A short proof of Allard's and Brakke's regularity theorems
We give new short proofs of Allard’s regularity theorem for varifolds with bounded first variation and Brakke’s regularity theorem for integral Brakke flows with bounded forcing. They are based on a decay of flatness, following …

From Besov to Sobolev: Looking at Non-Compact Embeddings
In this talk, we will explore the interplay between Besov and Sobolev spaces, focusing on describing properties for non-compact embedding (i.e., strict singularity, etc.). We will begin with an introduction to Besov spaces, highlighting their …
