abstract
Given a holomorphic self-map of complex projective space of degree larger than one, we prove that there exists a finite collection of totally invariant algebraic sets with the following property: given any positive closed (1,1)-current of mass 1 with no mass on any element of this family, the sequence of normalized pull-backs of the current converges to the Green current. Under suitable geometric conditions on the collection of totally invariant algebraic sets, we prove a sharper equidistribution result.

Log Calabi--Yau structure for endomorphisms on $\mathbf{P}^n$
For every q-polarized endomorphism of P^2, some iterate (P^2, R_{f^s}/(q^s-1)) is log canonical, settling Gongyo's conjecture for smooth projective surfaces.
