dedicated to professor w. t. tutte on the occasion of his eightieth birthday We characterize the symmetric (0, 1)-matrices that can be signed symmetrically so that every principal submatrix has determinant 0, \1. This characterization generalizes Tutte's famous characterization of totally unimodula
## Abstract In this paper the conjecture on the __k__th upper multiexponent of primitive matrices proposed by R.A. Brualdi and Liu are completely proved.
Let β denote the set of generalized doubly stochastic n = n real matrices; that n is matrices whose row and column sums are 1. The research in this paper concerns finding the closest matrix B\* in β to a given matrix A in M , the space of n = n n n
