Title: Determinantal inequalities for tridiagonal signsymmetric P
matrices
Abstract
The question of which ratios of products of minors are bounded over all
matrices in a given class has been of interest for quite some time. This
question has been resolved for the restricted case of principal minors for
the class of tridiagonal signsymmetric Pmatrices. In this talk we will
characterize all the inequalities that exist among products of general
minors of tridiagonal signsymmetric Pmatrices. Along the way we will
discuss the relevant history, necessary background, and the required
terminology. In addition, future avenues for research along these lines will
