On Fox’s trapezoidal conjecture (Combinatorics Seminar)
Karola Mészáros (Cornell)
Fox’s trapezoidal conjecture from 1962 states that the absolute values of the coefficients of the Alexander polynomial of alternating...
Representation stability via Young symmetrizers and a new ribbon basis for the rank-selected homology of the partition lattice (Combinatorics seminar)
Patricia Hersh (University of Oregon)
In this talk, we will begin with a quick review of group actions on posets, rank-selected homology of posets, representation stability, and...
