Dear All, 

This is a reminder of today's seminar from the series "Geometric
Structures".

Speaker: CARLOS BELTRÁN  [1](Universidad de Cantabria) [1]

Title: The average condition number of different problems, from a
geometric perspective 

Time: March 16, 2021, 4:15 pm (Rome Time)

Abstract:  

I will present the condition number of problems from a general
perspective as a measure of the stability of problems. Then I will
discuss how does this condition number look and interact with other
mathematical concepts in different problems which are very basic but are
still full of mysteries: polynomial solving, eigenvalue/eigenvector
problems or tensor decomposition problems. All the material will be
presented for a general audience. Different parts of what will be
presented has been done with different authors, for example the tensor
decomposition part has been done with Paul Breiding and Nick
Vannieuwenhoven. Check the following video for our result in 2 minutes:
