p-ADIC INTERPOLATION
نویسنده
چکیده
Although N is discrete in R, it is not discrete in Qp, and in fact has closure Zp. This raises the possibility of p-adically interpolating a sequence an, which is really a function n 7→ an on N, to a continuous function x 7→ ax with x ∈ Zp. Our basic question is this: when does a function f : N→ Qp extend to a continuous function Zp → Qp? We will look at some concrete examples, then see what a general continuous function Zp → Qp looks like, and finally discuss one approach to p-adic integration.

We study Rubin’s variant of the p-adic Birch and Swinnerton-Dyer conjecture for CM elliptic curves concerning certain special values of the Katz two-variable p-adic L-function that lie outside the range of p-adic interpolation.

متن کاملON CERTAIN SPECIAL VALUES OF THE KATZ TWO-VARIABLE p-ADIC L-FUNCTION
We develop a framework that enables us to study a broad class of special values of the Katz two-variable p-adic L-functions, including certain special values lying outside the range of p-adic interpolation.
متن کاملA p-ADIC WALDSPURGER FORMULA
In this article, we study p-adic torus periods for certain p-adic valued functions on Shimura curves coming from classical origin. We prove a p-adic Waldspurger formula for these periods, as a generalization of the recent work of Bertolini, Darmon, and Prasanna. In pursuing such a formula, we construct a new anti-cyclotomic p-adic L-function of Rankin– Selberg type. At a character of positive w...
متن کاملJACOBI FORMS AND A TWO-VARIABLE p-ADIC L-FUNCTION
Introduction. Consider a Jacobi form φ(τ, z) = ∑ n,r c(n, r)q ζ whose Fourier coefficients c(n, r) are algebraic numbers. Let p be an odd prime. In this paper we associate to φ a Λ-adic p-ordinary form in the sense of [4]. The construction comes from the map Dν introduced in [2], Theorem 3.1. This map associates to a Jacobi form a family of modular forms parametrised by ν. We obtain the two-var...
متن کاملCritical slope p-adic L-functions
Let g be an eigenform of weight k+2 on Γ0(p)∩Γ1(N) with p N . If g is non-critical (i.e. of slope less than k + 1), using the methods of [1, 20], one can attach a p-adic L-function to g which is uniquely determined by its interpolation property together with a bound on its growth. However, in the critical slope case, the corresponding growth bound is too large to uniquely determine the p-adic L...
