The $F$ -signature Function on the Big Cone

Seungsu Lee, Suchitra Pande

We define and study the $F$ -signature of big divisors on projective varieties in positive characteristics. For a normal projective variety $X$ , we show that the $F$ -signature funct…

The F-signature of Determinantal Rings

Hang Huang, Cheng Meng, Cheng Mend +2

Let $R_{n, p}$ be the determinantal hypersurface ring defined by the determinant of a generic $n \times n$ matrix in characteristic $p$ where $n \geq 2$ . In this paper, we obtain ex…

On positivity of the limit F-signature

Yuchen Liu, Suchitra Pande

We study a conjecture of Carvajal-Rojas, Schwede and Tucker which states that for a complex KLT singularity $(R, m)$ , the F-signatures of the reductions of $R$ to charac…
