Abstract

Let K/QpK / \mathbb{Q}_p be a finite Galois extension and DD a (φ,Γ)(\varphi, \Gamma)-module over the Robba-ring Brig,KB^{\dagger}_{\textrm{rig}, K}. We give a generalization of the Bloch-Kato exponential map for DD using continuous Galois-cohomology groups Hi(GK,W(D))H^i(G_K, W(D)) for the BB-pair W(D)W(D) associated to DD. We construct a big exponential map ΩD,h\Omega_{D,h} (hNh \in \mathbb{N}) for cyclotomic extensions of KK for DD in the style of Perrin-Riou using the theory of Berger's BB-pairs, which interpolates the generalized Bloch-Kato exponential maps on the finite levels.
