Title: Determinantal inequalities for tridiagonal sign-symmetric 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 sign-symmetric P-matrices. In this talk we will
characterize all the inequalities that exist among products of general
minors of tridiagonal sign-symmetric P-matrices. 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
