Necessary conditions for topological conjugacy of 3-manifolds diffeomorphisms with orbits of heteroclinic tangency

In present paper we consider a class of 3-manifolds' diffeomorphisms with finite hyperbolic chain recurrent set and finite number of heteroclinic tangencies' orbits. We prove that necessary conditions for topological conjugacy of two diffeomorphisms from this class is a generalization of moduli of stability for analogous two dimensional diffeomorphisms.
