Euler Lecture 2022

Prof. Dr. Wolfgang Lück

Titel: A Panorama of L²-Invariants

Abstract: We give a gentle survey about L²-invariants such as L²-Betti numbers and L²-torsion. They are modelled on their classical counterparts and defined in terms...

An algorithm for distributing weight over a finite graph (and its relation with Shintani zeta functions)

Diego Lopez (Uni Potsdam)

In this talk we will describe an algorithm to distribute some "n-dimensional weight" over the vertices of a graph, such that the weight on each vertex remains higher than a given bound. We will then...

Robust estimation of discrete distributions under local differential privacy

Julien Chhor

Joint work with Flore Sentenac (CREST)

Although robust learning and local differential privacy are both widely studied fields of research, combining the two settings is an almost unexplored topic. We...

Population models with seed bank: construction, duality and tree properties

Marta Dai Pra (HU Berlin)

This talk focuses on the study of population models with a seed bank, in particular presenting their construction from classical models, some duality results and tree properties.The first part is an...

Learning in High-Dimensional Feature Spaces Using ANOVA-Based Fast Matrix-Vector Multiplication

Theresa Wagner, TU Chemnitz

Kernel matrices are crucial in many learning tasks and typically dense and large-scale. Depending on the dimension of the feature space even the compu- tation of all its entries in reasonable time...
