Geometric Tools in Combinatorics (postponed in 2022)


Bogotá, Colombia


15/06/2021 to 26/06/2021


Combinatorics is at the center of a variety of areas in pure and applied mathematics. In recent years problems arising in algebra and geometry have been better understood and in many cases fully solved by exploiting their relation to certain combinatorial structures. At this school, we aim to introduce the participants to modern geometric techniques that have been used to solve long-standing conjectures in combinatorics and other areas.

Official language of the school: English. All the main activities and mini-courses will be given in English. Some contributed talks and posters given by students from the region will be in Spanish.
