Webinar: 1- and 2- dimensional holes in spaces by Prof. Matthias Kreck (Univ. Bonn)

Gonit Sora is organizing a webinar to be delivered by Prof. Matthias Kreck of the University of Bonn (Germany). The details are given below.

Date: 12 December, 2020 (Saturday)

Time: 3:30 pm IST

Title: 1- and 2- dimensional holes in spaces

Abstract: If we think about a hole for example in the plane, we imagine, that we have removed something from the plane. But imagine that we want to know what a hole is in the space we are living in, the universe. Or more generally what could it mean that a space which is not sitting a priory in a larger space has a hole? Once we know this we can formulate one of the most famous theorems in modern mathematics, which for a long time was a conjecture: The Poincaré conjecture.

About the Speaker: Prof. Matthias Kreck is a renowned mathematician known for his work in algebraic topology and differential topology. He is a professor in the Hausdorff Center for Mathematics at the University of Bonn in Germany, of which he was also the director from 2006 to 2011. Previously he was also the director of the renowned Mathematisches Forschungsinstitut Oberwolfach from 1994 to 2002. Prof. Kreck received his Diploma in 1970 and doctorate in 1972 from Bonn, under the supervision of the great German mathematician Friedrich Hirzebruch. Apart from Bonn and Oberwolfach, Prof. Kreck has also served in the universities at Wuppertal, Mainz and Heidelberg. He was also an editor of the journal Mathematische Annalen. Among his honours include, membership of the Heidelberg Academy of Sciences and Humanities and the Cantor medal of the German Mathematical Society.

The talk will be suitable for a general audience (college students are specially welcome), and will be held online via Zoom.

e-Certificates will be issued to participants who attend the talk on Zoom.
