Perfectoid overconvergent Siegel modular forms and the overconvergent Eichler--Shimura morphism
Hansheng Diao, Giovanni Rosso, Ju-Feng Wu
The aim of this paper is twofold. We first present a construction of the overconvergent automorphic sheaves for Siegel modular forms by generalising the perfectoid method, original…

Overconvergent Eichler-Shimura morphisms for
Hansheng Diao, Giovanni Rosso, Ju-Feng Wu
We construct explicit Eichler-Shimura morphisms for families of overconvergent Siegel modular forms of genus two. These can be viewed as -adic interpolations of the Eichler-Shim…
