On the regularity of the language of some T-ideals
We consider an algebra satisfying a polynomial identity (PI-algebra) and we define what the language generated by its T-ideal is. We conjecture the T-ideal of any PI-algebra is regular and in this paper we give results supporting the conjecture by computing the language of several classes of PI-algebras. Among them, we compute the language generated by some algebras of glued cells that are a useful tool to better understand the so-called Zariski-closed algebras.
期刊介绍:
Linear Algebra and its Applications publishes articles that contribute new information or new insights to matrix theory and finite dimensional linear algebra in their algebraic, arithmetic, combinatorial, geometric, or numerical aspects. It also publishes articles that give significant applications of matrix theory or linear algebra to other branches of mathematics and to other sciences. Articles that provide new information or perspectives on the historical development of matrix theory and linear algebra are also welcome. Expository articles which can serve as an introduction to a subject for workers in related areas and which bring one to the frontiers of research are encouraged. Reviews of books are published occasionally as are conference reports that provide an historical record of major meetings on matrix theory and linear algebra.
