Local cohomology and Segre products
Jiamin Li, Wenliang Zhang
We prove a Künneth formula for local cohomology of a Segré product of graded modules supported in a Segré product of ideals. In order to apply our formula to the study of cohomolog…
Socle degrees for local cohomology modules of thickenings of maximal minors and sub-maximal Pfaffians
Jiamin Li, Michael Perlman
Let be the polynomial ring on the space of non-square generic matrices or the space of odd-sized skew-symmetric matrices, and let be the determinantal ideal of maximal mino…
Singularities of generic linkage via Frobenius powers
Jiamin Li
Let be an equidimensional ideal of a ring polynomial over and let be its generic linkage. We prove that there is a uniform bound of the difference between…
On the generalized multiplicities of maximal minors and sub-maximal pfaffians
Jiamin Li
Let be a polynomial ring of generic variables (resp. a polynomial ring of skew-symmetric variables) over and…
A note on the multiplicities of the determinantal thickenings of maximal minors
Jiamin Li
Let be a polynomial ring of variables over and let be the determinantal ideal of maximal minors of . Using the representation…
