✦ Synopsis

This paper starts with some examples and quick results on the topological entropy of continuous functions. It discusses the topological entropy on Lie groups and proves their shift properties. It proves Fried's conjecture h(Β’~,) <_ h(Β’)+h(~) for affine maps on Lie groups. Moreover, Β’ and V do not have to commute. As a corollary, it proves that entropy is invariant with isometric endomorphisms of Lie groups. Also, it discusses algebraic entropy on elementary Abelian groups and Lie groups. It proves that the topological entropy is preserved when projected from Lie group ]R to its quotient space compact Lie group S 1 for continuous functions lifted from the quotient space and shows that algebraic entropy in general is strictly less than topological entropy.

This paper is devoted to an investigation of various dynamical concepts for group shift systems which are invariant by algebraic conjugacy (i.e., topological conjugacy preserving the group structure). The concept of controllability, which is stronger than topological transitivity, and the concept of

We show that each Mal'cev splittable -Lie algebra (i.e., each -Lie algebra where ad is splittable) with char = 0 may be realized as a splittable subalgebra of a gl V , where V is a finite-dimensional vector space over , and that each Mal'cev splittable analytic subgroup of a GL n , i.e., each subgro
