Frobenius Betti numbers and modules of finite projective dimension

Alessandro De Stefani, Craig Huneke, Luis Núñez-Betancourt

Let $(R, m, K)$ be a local ring, and let $M$ be an $R$ -module of finite length. We study asymptotic invariants, $β_{i}^{F} (M, R),$ defined by twisting with Frobenius the free r…

A sufficient condition for strong $F$ -regularity

Alessandro De Stefani, Luis Núñez-Betancourt

Let $(R, m, K)$ be an $F$ -finite Noetherian local ring which has a canonical ideal $I ⊊ R$ . We prove that if $R$ is $S_{2}$ and $H_{m}^{d - 1} (R / I)$ is a s…
