Workshop on Applied Algebra

TU Braunschweig, Germany, June 7-8, 2019

Description

The aim of this workshop is to bring together different researchers in applied algebra, very broadly interpreted, from in and outside of Germany.
Simultaneously, this is a kick-off workshop of the new research group on Applied Algebra at the Department of Mathematics at the TU Braunschweig.

Registration

In order to register for the conference, please send an email to Oguzhan Yürük via yuruk(at)math.tu-berlin.de including:

  1. Your name and your affiliation,
  2. An indication whether you anticipate to attend the dinner on Friday evening,
  3. OPTIONAL: An abstract, if you would like to present a poster,
  4. OPTIONAL: A notification, if you know that you will only attend on one day.
