E. V. Zhuzhoma, V. S. Medvedev National Research University "Higher School of Economics" (HSE), Moscow
Abstract:
An example of a diffeomorphism of the $3$-sphere with positive topological entropy which has a one-dimensional solenoidal basis set with a two-dimensional unstable and a one-dimensional stable invariant manifold at each point (in particular, the basis set is neither an attractor nor a repeller) is given. On the basis of this diffeomorphism, a nondissipative fast kinematic dynamo with a one-dimensional invariant solenoidal set is constructed.
Keywords:
basis set, solenoid.
