Symmetry p-adic invariant integral on Z_p for Bernoulli and euler polynomialsDec 02 2007The main purpose of this paper is to investigate several further interesting properties of symmetry for the p-adic invariant integral on Z_p.
An Invarian p-adic q-integral on the rings of p-adic integersJul 31 2006In the recent p-adic q-integral on the p-adic integers' rings was constructed >. The purpose of this paper is to give several interesting integral equation for the p-adic q-integerals on the rings of p-adic integers. As an integral equations, we will ... More
On p-adic q-l-functions and sums of powersMay 16 2006The purpose of this paper is to construct p-adic analytically continued function which interpolates q-Euler numbers at negative integer Finally, we give an explicit p-adic expansion as a power series in n.
q-Euler and Genocchi numbersJun 14 2005Carlitz has introduced an interesting $q$-analogue of Frobenius-Euler numbers in [4]. He has indicated a corresponding Stadudt-Clausen theorem and also some interesting congruence properties of the $q$-Euler numbers. In this paper we give another construction ... More
Multivariate p-dic L-functionMay 08 2005We construct multivariate p-adic L-function in the p-adic number fild by using Washington method.
