Local monodromy of unit root F-isocrystals from Shimura varieties

Tejasi Bhatnagar

We generalise a local $p$ -adic monodromy theorem of Igusa that studies the monodromy representation associated to the universal elliptic curve around a supersingular point of the m…

Covers of curves, Ceresa cycles, and Unlikely intersections

Tejasi Bhatnagar, Sheela Devadas, Toren D'Nelly-Warady +1

Fix a smooth, projective, geometrically integral curve $C$ of genus $g \geq 2$ over a characteristic zero field. We prove that the Ceresa cycle $Cer (C)$ of a v…
