Joint UAM-ICMAT Seminar
Algebra and Combinatorics
2015-2016

The Algebra and Combinatorics Seminar is a joint activity of the Departamento de Matemáticas at Universidad Autónoma de Madrid (UAM) and Instituto de Ciencias Matemáticas (ICMAT).

The seminar has a diverse range of interests in all aspects of modern algebra, combinatorics and group theory. This also includes theoretical computer science, applied algebra and theoretical physics!


Organizers:


Yago Antolin (UAM)

Ana Bravo (UAM)

Kurusch Ebrahimi-Fard (ICMAT)

Andrei Jaikin (UAM)


NOTE:

Unless otherwise indicated, the seminar meets on Friday at 11:30 a.m.

We alternatingly meet at the UAM mathematics department or at ICMAT.

If you are interested in speaking at the seminar, please contact one of the organizers.
