  In analogy to the topological entropy for continuous endomorphisms of totally
disconnected locally compact groups, we introduce a notion of topological
entropy for continuous endomorphisms of locally linearly compact vector spaces.
We study the fundamental properties of this entropy and we prove the Addition
Theorem, showing that the topological entropy is additive with respect to short
exact sequences. By means of Lefschetz Duality, we connect the topological
entropy to the algebraic entropy in a Bridge Theorem.
