to a cuspidal automorphic representation of gsp(4) over $\mathbb q$, one can associate a compatible system of galois representations $\{\rho_p\}_{p \; \mathrm{prime}}$. for $p$ sufficiently large, the deformation theory of the mod-$p$ reduction $\overline \rho_p$ is expected to be unobstructed -- meaning the universal deformation ring is a power series ring. the global obstructions to deforming $\overline \rho_p$ is controlled by certain adjoint bloch-kato selmer groups, which are expected to be trivial for $p$ large enough. \\ \\ i will talk about some recent results showing that there are no local obstructions to the deformation theory of $\overline \rho_p$ for almost all $p$. \\ \\ this is joint work with m. broshi, c. sorensen, and t. weston.
