A quantum Murnaghan--Nakayama rule for the flag manifold

Carolina Benedetti, Nantel Bergeron, Laura Colmenarejo +2

In this paper, we give a rule for the multiplication of a Schubert class by a tautological class in the (small) quantum cohomology ring of the flag manifold. As an intermediate ste…

Some problems at the interface of approximation theory and algebraic geometry

Frank Sottile

We sketch an assortment of problems that were posed -- and not yet solved -- during problem sessions at the conference ``Approximation Theory and Numerical Analysis meet Algebra, G…

Critical points of discrete periodic operators

Matthew Faust, Frank Sottile

We study the spectra of operators on periodic graphs using methods from combinatorial algebraic geometry. Our main result is a bound on the number of complex critical points of the…

Galois Groups in Enumerative Geometry and Applications

Frank Sottile, Thomas Yahl

As Jordan observed in 1870, just as univariate polynomials have Galois groups, so do problems in enumerative geometry. Despite this pedigree, the study of Galois groups in enumerat…
