We find polyhedral divisors corresponding to the torus action of complexity one on affine trinomial hypersurfaces. Explicit computations for particular classes of such hypersurfaces including Pham-Brieskorn surfaces and rational trinomial hypersurfaces are given.
Аннотация. Найден общий вид полиэдральных дивизоров, соответствующих естественному действию тора сложности один на аффинных триномиальных гиперповерхностях. Приведены примеры вычисления таких дивизоров для конкретных классов гиперповерхностей.
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.
