We present new, efficient algorithms for computations on separable matrix algebras over infinite fields. We provide a probabilistic method of the Monte Carlo type to find a generator for the center of a given algebra A β F mΓm over an infinite field F. The number of operations used is within a logar

## Abstract A characterization of the subdirectly irreducible separable dynamic algebras is presented. The notions develoβ ped for this study were also suitable to describe the previously found class of simple separable dynamic algebras (Β© 2010 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
In addition to a widely studied notion of homomorphisms of graphs and hypergraphs, [2, 5 , 6, 7, 9, 13, 141, we introduce the dual notion of cohomomorphisms. We shall concentrate on only a few aapects of these mappings, mostly with regard to intended applications, [lo, 111. Our basic motivation is t
