We study two properties of modules over an equicharacteristic or unramified local hypersurface R: decency and rigidity. We show that the vanishing of Hochster’s function θ(M,N), known to imply decent intersection, also implies rigidity. We investigate the vanishing of θ(M,N) to obtain new results about decency and rigidity over hypersurfaces. We employ a mixture of techniques from Commutative A...

But centralized content providers can always choose not to respond to requests for a specific file, making it difficul...
