Cartier algebras through the lens of $p$ -families

Anna Brosowsky

We study $F$ -graded systems of ideals in $R$ , which are sequences of ideals giving rise to Cartier algebras on $R$ . We identify how properties of these systems (or modifications of…

Limit $F$ -signature functions of two-variable binomial hypersurfaces

Anna Brosowsky, Izzet Coskun, Suchitra Pande +1

The $F$ -signature is a fundamental numerical invariant of singularities in positive characteristic. Its positivity detects strong $F$ -regularity, an important class of singularitie…

The Cartier core map for Cartier algebras

Anna Brosowsky

Let $R$ be a commutative Noetherian $F$ -finite ring of prime characteristic and let $D$ be a Cartier algebra. We define a self-map on the Frobenius split locus of the pai…
