Frobenius splitting and Möbius inversion
Allen Knutson
We show that the fundamental class in K-homology of a Frobenius split scheme can be computed as a certain alternating sum over irreducible varieties, with the coefficients computed…

Compatibly Frobenius split subschemes are rigid
Allen Knutson
Schwede proved very recently in arXiv:0901.1154 that in a quasiprojective scheme X with a fixed Frobenius splitting, there are only finitely many subschemes {Y} that are compatibly…
