Bertini theorems for Hilbert-Samuel multiplicity over finite fields

Rahul Ajit, Matthew Bertucci

Let $X$ be a quasiprojective subscheme of $P_{F_{q}}^{n}$ . We prove a Bertini theorem for Hilbert--Samuel multiplicity of $X$ ; that is, there exists a positive-densit…

$F$ -jumping numbers can be irrational

Rahul Ajit

Let $k$ be an $F$ -finite and infinite field of characteristic $p > 2$ . We show, there exist infinitely many $F$ -finite local domains $(R, m)$ which are not $Q$ -Gor…

On a Grauert-Riemenschneider vanishing theorem in dimension 3

Rahul Ajit

Suppose $R$ is an excellent ring of dimension $3$ and has rational singularities. Let $I ¨ : X ⟶ Spec R$ be a blow-up and $I ¨ : W ⟶ X$ be any pro…

Multiplier Modules of extended Rees algebras

Rahul Ajit

Given a local ring $(R, m)$ and an ideal $a$ of positive height, we give a way of computing multiplier module $J (I ¨ _{T}, t^{- I^»})$ for the extended Rees alg…

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, $I ¨ (I ¨ _{T}, t^{- I^»})$ , of the extended Rees algebra, $T =R…
