We prove the unirationality of many Del Pezzo surfaces of degree 2 with rational double points. Over perfect fields, we find all except three RDP Del Pezzo surfaces are non-minimal and thus unirational. Even if not perfect, we obtain a condition of the unirationality that was proved in smooth Del Pezzo surfaces of degree 2 by Salgado, Testa and Várilly-Alvarado. Using these results, we prove the unirationality over finite fields with at least 9 elements.
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.
