Test Modules of Extended Rees Algebras

Rahul Ajit, Hunter Simper

Given a reduced, local ring $R$ and an ideal $a$ of positive height, we give a decomposition of the test module, $τ (ω_{T}, t^{- λ})$ , of the extended Rees algebra, $T =R[\m…

Local Cohomology of Certain Determinantal Thickenings

Hunter Simper

Let $R = C [{x_{ij}}]$ be the ring of polynomial functions in $mn$ variables where $m > n$ . Set $X$ to be the $m \times n$ matrix in these variables and $I := I_{n} (X)$ the ideal…

Generic Generalized Diagonal Matrices

Vinh Nguyen, Hunter Simper

Generalized diagonal matrices are matrices that have two ladders of entries that are zero in the upper right and bottom left corners. The minors of generic generalized diagonal mat…
