On the Bloch--Kato conjecture for GSp(4) x GL(2)

Abstract

We prove the Bloch--Kato conjecture for certain critical values of degree 8 $L$-functions associated to cusp forms on ${\mathrm{GSp}}_4\times {\mathrm{GL}}_2$. We also construct a $p$-adic Eichler--Shimura isomorphism in Hida families for ${\mathrm{GSp}}_4$, relating $H^2$ of automorphic vector bundles with ${\mathbf{D}}_{\mathrm{cris}}$ of a subquotient of étale cohomology.
