Spectral properties of ergodic dynamical systems conjugate to their composition squares

Spectral properties of ergodic dynamical systems conjugate to their composition squares

Let $S$ and $T$ be automorphisms of a standard Borel probability space. Some ergodic and spectral consequences of the equation $ST=T^2S$ are given for $T$ ergodic and also when $T^n=I$ for some $n>2$. These ideas are used to construct examples of ergodic
