We can define p-adic Bernoulli polynomials by using q-integral on $\mathbb{Z}_p$ and Taekyun Kim's method.

But how can we define p-adic poly-Bernoulli numbers and polynomials by using integral on $\mathbb{Z}_p$?

I think what you are looking for is:

$$B_n^{k}(x)=\frac{Li_k (1-e^{-t})}{t}\int_{\mathbb{Z}_p}(x+y)^ndy$$

for $n\geq0$, and $Li_k$ the polylogarithmic function.

See for example, "Poly-Bernoulli Polynomials and Their Applications", by Kim, Jang and Seo.

Are those $t$'s supposed to be $n$'s? – Hurkyl Sep 30 '15 at 13:18
@Hurkyl Mmmm, no, I don't think so. The paper is avaible online, so I've included the link. – Myshkin Sep 30 '15 at 13:30
