A criterion for the total coordinate space of a trinomial hypersurface to be a hypersurface is found. An algorithm for calculating the Cox ring in explicit form is proposed, and criteria for the total coordinate space to be rational and factorial are obtained.
Keywords: affine variety, Cox ring, polyhedral divisor, rational variety.
Mots-clés : torus action
