Antiampleness and ampleness of the Frobenius cokernel
Devlin Mallory
We show that if is a smooth Fano variety containing a line or a conic with respect to , then the Frobenius cokernel $\mathcal B_X:=\mathrm{coker}(\mathcal O_X\to F_* \mat…
The tilting property for on Fano surfaces and threefolds
Devlin Mallory
Let be a smooth variety over a field of characteristic . It is a natural question whether the Frobenius pushforwards of the structure sheaf are tilting b…
Bigness of the tangent bundle of del Pezzo surfaces and -simplicity
Devlin Mallory
We consider the question of simplicity of a ring under the action of its ring of differential operators . We give examples to show that even when is Gorenstein and has…
Minimal log discrepancies of determinantal varieties via jet schemes
Devlin Mallory
We compute the minimal log discrepancies of determinantal varieties of square matrices, and more generally of pairs consisting of a determinantal…
Arc closures and the local isomorphism problem
Devlin Mallory
We give an answer in the "geometric" setting to a question of de Fernex, Ein, and Ishii, asking when local isomorphisms of -schemes can be detected on the associated maps of loc…
