A mod p Jacquet-Langlands relation and Serre filtration via the geometry of Hilbert modular varieties: Splicing and dicing
Fred Diamond, Payman Kassaei, Shu Sasaki
We consider Hilbert modular varieties in characteristic p with Iwahori level at p and construct a geometric Jacquet-Langlands relation showing that the irreducible components are i…
-adic Gross-Zagier formula at critical slope and a conjecture of Perrin-Riou
Kazim Büyükboduk, Robert Pollack, Shu Sasaki
Let be an odd prime. Given an imaginary quadratic field where splits with , and a -ordinary newform such that …
A Serre weight conjecture for geometric Hilbert modular forms in characteristic p
Fred Diamond, Shu Sasaki
Let p be a prime and F a totally real field in which p is unramified. We consider mod p Hilbert modular forms for F, defined as sections of automorphic line bundles on Hilbert modu…
Virtual turning points and bifurcation of Stokes curves for higher order ordinary differential equations
Takashi Aoki, Takahiro Kawai, Shunsuke Sasaki +2
For a higher order linear ordinary differential operator P, its Stokes curve bifurcates in general when it hits another turning point of P. This phenomenon is most neatly understan…
