Abstract

For a topological flow (V,ϕ)(V,\phi) - i.e., VV is a linearly compact vector space and ϕ\phi a continuous endomorphism of VV - we gain a deep understanding of the relationship between (V,ϕ)(V,\phi) and the Bernoulli shift: a topological flow (V,ϕ)(V,\phi) is essentially a product of one-dimensional left Bernoulli shifts as many as ent(V,ϕ)\mathrm{ent}^*(V,\phi) counts. This novel comprehension brings us to introduce a notion of corank for topological flows designed for coinciding with the value of the topological entropy of (V,ϕ)(V,\phi). As an application, we provide an alternative proof of the so-called Bridge Theorem for locally linearly compact vector spaces connecting the topological entropy to the algebraic entropy by means of Lefschetz duality.
