Abstract
We show that p-adic families of modular forms give rise to certain p-adic Abel-Jacobi maps at their p-new specializations. We introduce the concept of differentiation of distributions, using it to give a new description of the Coleman-Teitelbaum cocycle that arises in the context of the \(\mathcal {L}\)-invariant.
Résumé
Nous associons certaines applications p-adiques d’Abel-Jacobi aux familles analytiques de formes modulaires à ses poids nouveaux en p. Nous introduisons le concept de la dérivée d’une distribution. Utilisant ce concept, nous donnons une nouvelle perspective sur le cocycle de Coleman-Teitelbaum dans le contexte de l’invariant \(\mathcal {L}\).

Indeed let K be the finite kernel, so that we may write \(\mathbf {q} _{\Gamma _{N^{+},N^{-}}}=K\times \mathbf {q}_{\Gamma _{N^{+},N^{-}}}^{\prime } \) with \(\mathbf {q}_{\Gamma _{N^{+},N^{-}}}^{\prime }\subset \mathbf {q} _{\Gamma _{N^{+},N^{-}}}\) such that \({{\mathrm{ord}}}\) is injective on \(\mathbf {q} _{\Gamma _{N^{+},N^{-}}}^{\prime }\) and such that the image is a lattice. Then, according to [18, §6.4], \(\frac{\mathbf {T}_{\Gamma _{N^{+},N^{-}}}}{\mathbf {q}_{\Gamma _{N^{+},N^{-}}}^{\prime }}\) is an analytic torus. But since K is finite, \(\frac{\mathbf {T}_{\Gamma _{N^{+},N^{-}}}}{\mathbf {q}_{\Gamma _{N^{+},N^{-}}}}=( \frac{\mathbf {T} _{\Gamma _{N^{+},N^{-}}}}{\mathbf {q}_{\Gamma _{N^{+},N^{-}}}^{\prime }}) ^{K}\) exists (again by [18, §6.4]) and it is also an analytic torus.
Indeed, we have \(I_{\ell }^{0}\circ \iota =\ell \circ I_{\times }^{0}\) for \( \ell ={{\mathrm{ord}}}\) or \(\log _{0}\) by the analogue of (32) It follows that the \(\mathcal {L}\)-invariant of [28] considered in [35] is the \(\mathcal {L}\)-invariant of the monodromy module attached to \(J_{\Gamma _{N^{+},N^{-}}}\), i.e. the \(\mathcal {L}\) -invariant of \(J_{\Gamma _{N^{+},N^{-}}}\). Hence, the main result of [35] gives the required lift of the main result of [16].
We write \(V\otimes _{\iota }W\) (resp. \(V\otimes W\)) to denote \(V\otimes _{K}W\) with the inductive (resp. projective) tensor topology. Also, a morphism \(V\rightarrow W\) is a continuous, K-linear if V and W are locally convex spaces. Completion means Hausdorff completion.
Since the multiplication law \(\mathcal {D}\left( T\right) \times \mathcal {D} \left( T\right) \rightarrow \mathcal {D}\left( T\right) \) is only separately continuous, \(\mathcal {D}\left( T\right) \) is not a locally convex algebra. When T is compact the multiplication law is continuous and \({{\mathrm{Hom}}}_{\mathcal { L}}\left( \mathcal {D}\left( T\right) ,\mathcal {O}\right) \) is the space of morphisms of locally convex algebras.
We remark that [40, Theorem 2.2] can be refined to a bicontinuous isomorphism and extended to the case where the manifold is strictly paracompact.
Suppose that \(\left( F_{i}\right) \rightarrow F\) is a net in \(\mathcal {A}_{ \mathbf {k}}\left( X\right) \) converging to \(F\in \mathcal {A}\left( X, \mathcal {O}\right) \). If \(t\in T\) let \(t:X\rightarrow X\) be the locally analytic map given by left multiplication by t, so that \(t^{*}\left( F_{i}\right) \rightarrow t^{*}\left( F\right) \) Since the multiplication in \(\mathcal {O}\) is separately continuous, \(G\mapsto t^{ \mathbf {k}_{2}}G\) is continuous and \(t^{\mathbf {k}_{2}}F_{i}\rightarrow t^{ \mathbf {k}_{2}}F\). Since \(t^{*}\left( F_{i}\right) =t^{\mathbf {k} _{2}}F_{i}\) we deduce that \(t^{*}\left( F\right) =t^{\mathbf {k}_{2}}F\) for every \(t\in T\), meaning that \(F\in \mathcal {A}_{\mathbf {k}}\left( X\right) \).
According to [32, PartII, Ch.III §12 Theorem1] there exists at most one p-adic manifold structure on \(\overline{X}\) making \(\pi :X\rightarrow \overline{X}\) a topological quotient in such a way that \(\pi \) is a submersion. See [32, PartII, Ch.III §12 Theorem 2] for natural conditions granting the existence of such a quotient.
We have indeed.
