Let A an n×n p.s.d hermitian matrix, let r1…rn denote the row sums of A, and suppose [image omitted] . Denote by pk(A) the sum of permanents of all kxk submatrices of A. It is shown that of 2≤k≤n the [image omitted] It follows that of JR denotes the n×n matrix whose (i,j) entry is [image omitted] then the function Pk((1-t)JR+tA) is non-decreasing on [0,1].
