Abstract: We prove that the group of automorphisms of any quasi-projective surface S in finite characteristic has the p-Jordan property. Also we give a list of examples which can possibly lead to a construction of a… read more here.

Abstract: We investigate int-amplified endomorphisms on normal projective surfaces. We prove that the output of the equivariant MMP is either a Q-abelian surface, a (equivariant) quasi-\'etale quotient of a smooth projective surface, a Mori dream space,… read more here.
