Parabolic-equivariant modules over polynomial rings in infinitely many variables

Teresa Yu

We study the category of -equivariant modules over the infinite variable polynomial ring, where denotes the subgroup of the infinite general linear group $…

Jets and principal components of monomial ideals, and very well-covered graphs

Federico Galetto, Nicholas Iammarino, Teresa Yu

Motivated by using combinatorics to study jets of monomial ideals, we extend a definition of jets from graphs to clutters. We offer some structural results on their vertex covers,…

Polynomial functors on flags

Teresa Yu

We study generalizations of Schur functors from categories consisting of flags of vector spaces. We give different descriptions of the category of such functors in terms of represe…

Moment varieties from inverse Gaussian and gamma distributions

Oskar Henriksson, Lisa Seccia, Teresa Yu

Motivated by previous work on moment varieties for Gaussian distributions and their mixtures, we study moment varieties for two other statistically important two-parameter distribu…

Standard monomial theory modulo Frobenius in characteristic two

Laura Casabella, Teresa Yu

Over a field of characteristic two, we develop a theory of standard monomials for polynomial rings modulo a Frobenius power of the maximal ideal generated by all variables. As a re…

On Virtually Cohen-Macaulay Simplicial Complexes

Nathan Kenshur, Feiyang Lin, Sean McNally +2

We examine virtual resolutions of Stanley-Reisner ideals for a product of projective spaces. In particular, we provide sufficient conditions for a simplicial complex to be virtuall…

Completions of Uncountable Local Rings with Countable Spectra

S. Loepp, Teresa Yu

We find necessary and sufficient conditions for a complete local (Noetherian) ring to be the completion of an uncountable local (Noetherian) domain with a countable spectrum. Our r…

Completions of Countable Excellent Domains and Countable Noncatenary Domains

S. Loepp, Teresa Yu

We find necessary and sufficient conditions for a complete local ring containing the rationals to be the completion of a countable excellent local (Noetherian) domain. Furthermore,…

Gonality sequences of graphs

Ivan Aidun, Frances Dean, Ralph Morrison +2

To any graph we associate a sequence of integers called the gonality sequence of the graph, consisting of the minimum degrees of divisors of increasing rank on the graph. This is a…

Extended Nestohedra and their Face Numbers

Quang Dao, Christina Meng, Julian Wellman +3

Nestohedra are a family of convex polytopes that includes permutohedra, associahedra, and graph associahedra. In this paper, we study an extension of such polytopes, called extende…

Multi-color forcing in graphs

Chassidy Bozeman, Pamela E. Harris, Neel Jain +2

Let be a finite connected graph along with a coloring of the vertices of using the colors in a given set . In this paper, we introduce multi-color forcing, a gener…

Graphs of gonality three

Ivan Aidun, Frances Dean, Ralph Morrison +2

In 2013, Chan classified all metric hyperelliptic graphs, proving that divisorial gonality and geometric gonality are equivalent in the hyperelliptic case. We show that such a clas…

Treewidth and gonality of glued grid graphs

Ivan Aidun, Frances Dean, Ralph Morrison +2

We compute the treewidth of a family of graphs we refer to as the glued grids, consisting of the stacked prism graphs and the toroidal grids. Our main technique is constructing str…
