Let M be a class of matrices, M\* a proper subclass of M, and $(n) = $(y6; M, M\*) the largest integer k with the property that every n x n matrix of class M possesses a k x k submatrix of class M\*. In the present paper we seek to estimate $(n) when n is large for two particular specifications of t
## Abstract We study the properties of the positive principal eigenvalue of a degenerate quasilinear elliptic system. We prove that this eigenvalue is simple, unique up to positive eigenfunctions and isolated. Under certain restrictions on the given data, the regularity of the corresponding eigenfu
The nonsingular submatrices of maximum order of the complete and the reduced incidence matrices over the real jield of a graph are shown to be in one-to-one correspondence with the odd generalized circuits and the odd generalized k-trees of the graph, respectively. It is also shown that the positiv
