Аннотация	We consider a class $SD(M^3)$ of gradient-like diffeomorphisms on closed 3-manifolds $M^3$ that have surface dynamics. In~\cite{GrGuPo-rhd} it was proven that the ambient manifold $M^3$ for such diffeomorphisms is a mapping torus $M_{g,\tau}$, $g\geq 0$, and the number of non-compact heteroclinic curves is no less than $12g$. In this paper it is established that for any integer $n\geq 12g$ there exists a mapping torus $M_{g,\tau(n)}$ and a diffeomorphism from the class $SD(M_{g,\tau(n)})$ having exactly $n$ heteroclinic curves.
Ключевые слова	Heteroclinic curve, gradient-like diffeomorphism, mapping torus
