The -signature Function on the Big Cone
Seungsu Lee, Suchitra Pande
We define and study the -signature of big divisors on projective varieties in positive characteristics. For a normal projective variety , we show that the -signature funct…
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 , the F-signatures of the reductions of to charac…
Plus-pure thresholds of some cusp-like singularities in mixed characteristic
Hanlin Cai, Suchitra Pande, Eamon Quinlan-Gallego +2
Log-canonical and -pure thresholds of pairs in equal characteristic admit an analog in the recent theory of singularities in mixed characteristic, which is known as the plus-pur…
A Frobenius Version of Tians Alpha-Invariant
Suchitra Pande
For a pair (X,L) consisting of a projective variety X over a perfect field of characteristic p>0 and an ample line bundle L on X, we introduce and study a positive characteristic a…
