On existence of an endomorphism of $2$-torus with strictly invariant repeller
E. D. Kurenkov1
Annotation | In the article we construct an axiom $A$ endomorphism $f$ of 2-torus with nonwondering set that contains one-dimensional contracting repeller satisfying following properties: 1) $f(\Lambda)= \Lambda$, $f^{-1}(\Lambda)= \Lambda$; 2) $\Lambda$ is locally homeomorphic to the product of the Cantor set and the interval; 3) $T^2\setminus\Lambda$ consist of a countable family of disjoint open disks. The key idea of construction consists in applying the surgery introduced by S. Smale \cite{Sm} to an algebraic endomorphism of the two-torus. We present the results of computational experiment that demonstrate correctness of our construction. Suggested construction reveals significant difference between one-dimensional basic of endomorphisms and one-dimensional basic sets of corresponding diffoemorphisms. In particular, the result contrasts with the fact that wondering set of axiom $A$ diffeomorphism consist of a finite number of open disks in case of spaciously situated basic set \cite{Gr75}. |
