Tensor products of modules, rigidity and local cohomology.
The equations of space curves on a quadric.
The homogeneous ideals of curves in a double plane have been studied by Chiarli, Greco, Nagel. Completing this work we describe the equations of any curve that is contained in some quadric. As a consequence, we classify the Hartshorne-Rao modules of such curves.
The geometry of the local cohomology filtration in equivariant bordism.
The injectivity of Frobenius acting on cohomology and local cohomology modules.
Tight closure and the Kodaira Vanishing Theorem.
Topological computation of local cohomology multiplicities.
We express the Lyubeznik numbers of the local ring of a complex isolated singularity in terms of Betti numbers of the associated real link.
Toward parametric Cohen-Macaulayfication of two-dimensional finite local cohomology domains.
