โœฆ Synopsis


Let A : (aij) be an m x n matrix. There is a natural way to associate a poset PA with A. Let xt,... ,xm and Yl,... ,Yn be disjoint sets of m and n elements, respectively, and define x~ < y/if and only if aij ยข 0. A jump in a linear extension of PA iS a pair of consecutive elements which are incomparable in P. The maximum jump number over a class of n x n matrices of zeros and ones with constant row and column sum k, M(n, k), has been

We show that for n >~ 5 the maximum determinant of an n x n matrix of zeros and ones whose zeros form an acyclic pattern is [(n-1)/2] [(n-1)/2] and characterize the case of equality. 1 We are indebted to H.J. Ryser for some of the references in this paragraph.

We investigate the chromatic number of a class of matrices of O's and l's with given row and column sum vectors, equivalently the chromatic number of hypergraphs with given degree and dual-degree sequences.
