The parity module of a matroid

Tom Braden, June Huh, Jacob P. Matherne +2

We introduce the parity module of a matroid with coefficients in a field $k$ . When $k$ has characteristic zero, we show that the parity module of a matroid is iso…

Chromatic symmetric functions of claw-free graphs are not Schur positive

Jacob P. Matherne, Alejandro H. Morales

Chromatic symmetric functions are well-studied symmetric functions in algebraic combinatorics that generalize chromatic polynomials of graphs. In 1995, Stanley introduced these sym…

Universality theorems for generalized splines

Jacob Matherne, Eric Ramos, Julianna Tymoczko

We study generalized splines from the perspective of the representation theory of the category of graphs with contractions. Our main theorem proves a kind of finite generation, whi…
