In this paper we outline a Matrix Ansatz approach to some problems of combinatorial enumeration. The idea is that many interesting quantities can be expressed in terms of products of matrices, where the matrices obey certain relations. We illustrate this approach with applications to moments of orthogonal polynomials, permutations, signed permutations, and tableaux. To Dennis Stanton with admir...

The structure multivector is a new approach for analyzing the local properties of a two-dimensional signal (e.g. images). It combines the classical concepts of the structure tensor and the analytic signal in a new way. This has been made possible by using a representation in the algebra of quaternions. The resulting method is linear and of low complexity. The filter-response includes local phas...

A keyH is a semi-standard tableau of partition shape whose evaluation is a permutation of the shape. We give a necessary and sufficient condition that the Knuth class of a key equals the set of shuffles of its columns. In particular, on a three-letter alphabet the Knuth class of a key equals the set of shuffles of its columns, and on a four-letter alphabet, the Knuth class of a key is either th...
