EMS Summer School on Multigraded Algebra and Applications

Wednesday, August 17, 2016 (All day) to Wednesday, August 24, 2016 (All day)

The goal of this school is to present the main research directions of combinatorial commutative algebra with a strong focus on its applicability in various fields, like combinatorics, statistics, and biology.

For this purpose we plan to offer integrated courses where the theoretical developments are directly motivated by topics from the above mentioned fields. This activity will be complemented by informal tutorial sessions, computer demos, and problem sessions lead by senior participants, where the audience has the chance to ask questions and discuss aspects of the material.

The EMS Summer School on Multigraded Algebra and Applications will take place   in the frame of the National School of Algebra, an event with a long tradition in Romania which is organized by the Ovidius University of Constanta, the Simion Stoilow Institute of Mathematics of the Romanian Academy, Bucharest, and the University of Bucharest.

The organizers gratefully acknowledge the financial support awarded by the European Mathematical Society and Foundation Compositio Mathematica .
