Certain Nonbarycentric Cohesive Matrices
Fischer, Ismor,Hwang, Suk-Eeun 경북대학교 위상수학 기하학연구센터 1995 硏究論文集 Vol.5 No.-
Let P_(n) denote the permutation matrix corresponding to the n-cycle (1 2 … n) and let K_(2) denote the 2×2 matrix of l's. In this paper we investigate the permanent minimization problem over the face determined by (I_n+P_n)??K_(2) of the polytope of n×n doubly stochastic matrices, with which we also answer a couple of open questions in the theory of permanents.
