F-signature of pairs: Continuity, p-fractals and minimal log discrepancies
Manuel Blickle, Karl Schwede, Kevin Tucker
This paper contains a number of observations on the {-signature} of triples $(R,Δ,\ba^t)$ introduced in our previous joint work. We first show that the -signature $s(R,Δ,\ba^…
A dual to tight closure theory
Neil Epstein, Karl Schwede
We introduce an operation on modules over an -finite ring of characteristic . We call this operation \emph{tight interior}. While it exists more generally, in some cases this…
F-signature of pairs and the asymptotic behavior of Frobenius splittings
Manuel Blickle, Karl Schwede, Kevin Tucker
We generalize -signature to pairs where is a Cartier subalgebra on as defined by the first two authors. In particular, we show the existence and positivity of th…
An algorithm for computing compatibly Frobenius split subvarieties
Mordechai Katzman, Karl Schwede
Let be a ring of prime characteristic , and let denote viewed as an -module via the th iterated Frobenius map. Given a surjective map …
