High Frobenius pushforwards generate the bounded derived category

Matthew R. Ballard, Srikanth B. Iyengar, Pat Lank +2

This work concerns generators for the bounded derived category of coherent sheaves over a noetherian scheme $X$ of prime characteristic. The main result is that when the Frobenius…

Ind-étale vs Formally étale

Shubhodip Mondal, Alapan Mukhopadhyay

We show that when $A$ is a reduced algebra over a characteristic zero field $k$ and the module of Kähler differentials $Ω_{A / k} = 0$ , then $A$ is ind-étale, partially answering a que…

Multi-point Seshadri constants on ruled surfaces

Krishna Hanumanthu, Alapan Mukhopadhyay

Let $X$ be a surface and let $L$ be an ample line bundle on $X$ . We first obtain a lower bound for the Seshadri constant $ε (X, L, r)$ , when $r \geq 3$ . We then assume that $…
