Abstract

Let XX be a normal projective variety admitting a polarized or int-amplified endomorphism ff. We list up characteristic properties of such an endomorphism and classify such a variety from the aspects of its singularity, anti-canonical divisor and Kodaira dimension. Then we run the equivariant minimal model program with respect to not just the single ff but also the monoid SEnd(X)SEnd(X) of all surjective endomorphisms of XX, up to finite-index. Several applications are given. We also give both algebraic and geometric characterizations of toric varieties via polarized endomorphisms.
