Abstract:For an arbitrary ample divisor A in smooth del Pezzo surface S of degree 1, we verify the condition of the polarization (S,A) to be K‐stable and it is a simple numerical condition.

We give an explicit counter-example to a conjecture of Kyusik Hong and Joonyeong Won about α-invariants of polarized smooth del Pezzo surfaces of degree one.All varieties are assumed to be algebraic, projective and defined over C.

We give an explicit counter-example to a conjecture of Kyusik Hong and Joonyeong Won about α-invariants of polarized smooth del Pezzo surfaces of degree one.All varieties are assumed to be algebraic, projective and defined over C.
We give a simple sufficient condition for K-stability of polarized del Pezzo surfaces and for the existence of a constant scalar curvature Kähler metric in the Kähler class corresponding to the polarization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
