Knuth-Bendix completions of the equational theories of k 2 commuting group endomorphisms are obtained, using automated theorem proving and modern termination checking. This impro...
In this paper we emphasize the links between model theory and tilings. More precisely, after giving the definitions of what tilings are, we give a natural way to have an interpreta...
We show the non-arithmeticity of 1st order theories of lattices of n sentences modulo provable equivalence in a formal theory, of diagonalizable algebras of a wider class of arithm...
Abstract. We outline a general theory of graph polynomials which covers all the examples we found in the vast literature, in particular, the chromatic polynomial, various generaliz...
We consider matrix groups, specified by a list of generators, over finite fields. The two most basic questions about such groups are membership in and the order of the group. Even...
