We investigate the measure-theoretic entropy of the discrete geodesic flow with respect to invariant probability measures.
WebApr 13, 2024 · We will refer to the spectrum of such a flow as a tensor simple spectrum. A flow \ {T_t\}, t\in\mathbb {R}, on a Lebesgue space (X, \mu) is a continuous embedding of the group \mathbb {R} into the group of all automorphisms of the space (X,\mu). A measure-preserving flow \ {T_t\} induces the unitary flow defined by T_tf (x)= f (T_tx) (we use ...
