Abstract: The foundation of a matroid is an algebraic
invariant that controls representations over any partial field,
hyperfield, or more generally, any pasture. We show that, under
certain conditions, the foundation of a generalized parallel...
Abstract: After a gentle introduction to matroids, I
will present parts of a new OSCAR software module for matroids
through several examples. I will focus on computing the moduli
space of a matroid which is the space of all arrangements of...
Abstract: A toric vector bundle is a torus equivariant
vector bundle on a toric variety.
We begin by recalling the classification of toric
vector bundles due to Klyachko. The Klyachko data of a toric vector
bundle can be interpreted as a "piecewise...
Summary: This event aims to foster
collaboration between combinatorialists and amplitudologists in two
ways: first by bridging language and concept barriers, and second
by highlighting open problems of mutual interest.

During the 2024-25 academic year the School will have a special
program on Algebraic and Geometric Combinatorics. June Huh from
Princeton University will be the Distinguished Visiting
Professor.
Mathematical objects often have a combinatorial...
