Nondissipativ kinematic dynamics on lenses

E. V. Zhuzhoma1, V. S. Medvedev2

AnnotationIn the paper, one constructs smooth (infinitely many differentiable) diffeomorphism of three dimensional lens (a closed three-manifold that is sheet-finitely covered by three-dimensional sphere) which has a positive entropy and keeps the volume in some neighborhood of its non-wandering set (note that in the list of lens, we include a three-dimensional sphere). In addition, there is a neighborhood in the space of diffeomorphisms that is conservative in some neighborhood of its non-wandering set which is consisted of diffeomorphisms with a positive entropy (i.e., the diffeomorphism constructed is relatively stable in the class of diffeomorphisms). Due to the properties, the diffeomorphism constructed can be a model of non-dissipative kinematic fast dynamo (the open question is either the diffeomorphism constructed the model of a middle or dissipative fast dynamo).
