چکیده
Proof. Now suppose that ρp is absolutely reducible and we want to show that for any other λ ∈ Spec(E), ρλ is also absolutely reducible. Note that there exists a finite extension K over Ep such that ρp is reducible. Then there is a vector e1 in the underline space V ′ = V ⊗Ep K such that G is stable over e1. Let χ1 be the character of G acts on e1, χ2 the character G acts on V ′/K · e1. Since χi is p-adic Hodge-Tate (i.e. potentially-semi-stable) character. Using Fontaine’s classification,

Potential Modularity and Applications
In our seminar we have been working towards a modularity lifting theorem. Recall that such a theorem allows one (under suitable hypotheses) to deduce the modularity of a p-adic Galois representation from that of the corresponding mod p representation. This is a wonderful theorem, but it is not immediately apparent how it can be applied: when does one know that the residual representation is mod...
متن کاملProving modularity for a given elliptic curve over an imaginary quadratic field
We present an algorithm to determine if the L-series associated to an automorphic representation and the one associated to an elliptic curve over an imaginary quadratic field agree. By the work of Harris-Soudry-Taylor, Taylor, and Berger-Harcos, we can associate to an automorphic representation a family of compatible -adic representations. Our algorithm is based on Faltings-Serre’s method to pr...
متن کاملp-adic Modular Forms: An Introduction
Serre in the 1970s was the first to formalize such a question on the way to constructing p-adic L-functions, by way of developing the notion of a p-adic modular form to be the p-adic limit of some compatible family of q-expansions of classical modular forms. Katz came along fairly soon afterwards and generalized the theory to a much more geometric context, and showed that Serre’s p-adic forms e...
متن کاملp-adic Shearlets
The field $Q_{p}$ of $p$-adic numbers is defined as the completion of the field of the rational numbers $Q$ with respect to the $p$-adic norm $|.|_{p}$. In this paper, we study the continuous and discrete $p-$adic shearlet systems on $L^{2}(Q_{p}^{2})$. We also suggest discrete $p-$adic shearlet frames. Several examples are provided.
متن کاملExpansions of Modular Forms and Their Interpolation Properties
We define a power series expansion of a holomorphic modular form f in the p-adic neighborhood of a CM point x of type K for a split good prime p. The modularity group can be either a classical conguence group or a group of norm 1 elements in an order of an indefinite quaternion algebra. The expansion coefficients are shown to be closely related to the classical Maass operators and give p-adic i...
