Lomonosov Moscow State University

Abstract: We describe homogeneous locally nilpotent derivations of the algebra of regular functions for a class of affine trinomial hypersurfaces. This class comprises all nonfactorial trinomial hypersurfaces.

Keywords: affine hypersurface, torus action, graded algebra, derivation.
