We study the connection between multimatroids and moduli spaces of rational curves with
cyclic action. Multimatroids are generalizations of matroids and delta-matroids that naturally …

We define and study q-delta-matroids, and qg-matroids. These objects are analogues, for
finite-dimensional vector spaces over finite fields, of delta-matroids and g-matroids arising …

Wonderful varieties are certain smooth projective varieties constructed from linear
subspaces of a coordinated vector space. We establish a positivity property for Grothendieck …

Type $ A $ and type $ B $ permutohedral varieties are classic examples of mathematics, and
their topological invariants are well known. This naturally leads to the investigation of the …
