A Bernoulli linked-twist map in the plane
James Springham, Stephen Wiggins
We prove that a Lebesgue measure-preserving linked-twist map defined in the plane is metrically isomorphic to a Bernoulli shift (and thus strongly mixing). This is the first such r…

Ergodic properties of linked-twist maps
James Springham
We study a class of homeomorphisms of surfaces collectively known as linked-twist maps. We introduce an abstract definition which enables us to give a precise characterisation of a…
