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