FACULTY OF

MATHEMATICS

On Monday, July 15, 2019, the IAG went on its yearly institute trip to visit Dessau. We first had tours at the Bauhaus and the Master's Houses. After a good meal in the historic Bauhaus canteen, we used the afternoon for a walk through the Georgium. There, the above photo was taken.

At the invitation of the IAG, Kai-Uwe Schmidt (Paderborn University) will talk about Unusually nonlinear functions at the Mathematisches Kollquium of the Mathematics Department. The talk will take place on July 4, 2019, at 5 pm in room G03-206. From 2012 to 2015, Kai-Uwe Schmidt was a postdoc at the IAG, in 2014 he habilitated in Magdeburg. Recently, he was awarded the Hall medal 2018 for outstanding achievements by researchers who are not older than 40 years by the Institute for Combinatorics and its Applications.

Abstract

In this talk I consider functions on a vector space over a finite field, including Boolean functions. The main question I address is: How far can such functions be away from the set of linear functions. This question is of vital importance in cryptography and is in disguise an old puzzle in coding theory. I shall explain the history of this problem and then explain how probabilistic and number-theoretic methods can be used to show that there are indeed functions with maximum possible distance to the set of linear functions.

It has been several months since Prof. Dr. Stefanie Rach and Prof. Dr. Petra Schwer joined the IAG, Prof. Dr. Rach as head of the Mathematics Education Group and Prof. Dr. Schwer as head of the Geometry Group. They will both give their inaugural lectures in a joint event on June 27, 2019.

Programm

Afterwards there will be a small reception.

In June 2019 there will be the following talks at the IAG-Oberseminar (Tue, 1-2 pm, G02-20). All that are interested are cordially invited.

In May  2019 there will be the following talks at the IAG-Oberseminar (Tue, 1-2 pm, G02-20). All that are interested are cordially invited.
