The Workshop of the Seminar of Representation Theory and Related Areas, a series of meetings started in 2011, will be held this year at the Center of Mathematics of the University of Porto (CMUP), in collaboration with the PhD Program in Mathematics PIUDM, a joint PhD program between the Universities of Coimbra and of Porto.

This series aims to pursue and develop interactions between Representation Theory, Geometry, Combinatorics and other relevant areas, promoting interactions between the national and international community in these areas. 

Participation is free and open to anyone with interests in these and other related areas and the participation of PhD students is highly encouraged, but registration by email is necessary to guarantee access to the event and the coffee-breaks. Use this form to Register.

See the workshop webpage for more details, including abstracts, location and social activities.
