摘要

证明了二维环面到自身的连续映射在基群上引起双曲作用的每一个同伦类中,只要不存在展开映射,就存在一个-自同态,其非游荡集由一个吸引双曲汇和一个非平凡的一维坍缩排斥组成,它是一维可定向层合,局部同同态于康托集与线段的直积。此外,该斥力的切空间的不稳定不变子束具有唯一性。参考书目:23篇。

On -endomorphisms of the two-dimensional torus
It is proved that in each homotopy class of continuous mappings of the two-dimensional torus to itself that induce a hyperbolic action on the fundamental group, as long as it is free of expanding mappings, there exists an -endomorphism whose nonwandering set consists of an attracting hyperbolic sink and a nontrivial one-dimensional collapsing repeller, which is a one-dimensional orientable lamination, locally homeomorphic to the direct product of a Cantor set and a line segment. Moreover, the unstable -invariant subbundle of the tangent space to the repeller has the property of uniqueness. Bibliography: 23 titles.
