A generalization of Kato's local $\varepsilon$-conjecture for $(\varphi,\Gamma)$-modules over the Robba ring

Abstract

We generalize Kato’s (commutative) $p$-adic local $\epsilon$-conjecture for families of $\left(\phi ,\Gamma \right)$-modules over the Robba rings. In particular, we prove the essential parts of the generalized local $\epsilon$-conjecture for families of trianguline $\left(\phi ,\Gamma \right)$-modules. The key ingredients are the author’s previous work on the Bloch–Kato exponential map for $\left(\phi ,\Gamma \right)$-modules and the recent results of Kedlaya, Pottharst and Xiao on the finiteness of cohomology of $\left(\phi ,\Gamma \right)$-modules.
