Abstract:

Let $X$ be a compact complex non-Kähler manifold and let $f$ be a dominant meromorphic self-map of $X$. Examples of such maps are self-maps of Hopf manifolds, Calabi-Eckmann manifolds, non-tori nilmanifolds, and their blowups. We prove that if $f$ has a dominant topological degree, then $f$ possesses an equilibrium measure $\mu$ satisfying well-known properties as in the Kähler case. The key ingredients are the notion of weakly d.s.h. functions substituting d.s.h. functions in the Kähler case and the use of suitable test functions in Sobolev spaces. A large enough class of holomorphic self-maps with a dominant topological degree on Hopf manifolds is also given.
