Resumen de Ä-product of Markov matrices.

J. P. Lampreia, A. Rica da Silva, J. Sousa Ramos

• In this paper we introduce a Ä-operation over Markov transition matrices, in the context of subshift of finite type, reproducing symbolic properties of the iterates of the critical point on a one-parameter family of unimodal maps. To the *-product between kneading sequences we associate a Ä-product between the corresponding Markov matrices.
