Abstract
We aim to introduce arbitrary complex order Hermite-Bernoulli polynomials and Hermite-Bernoulli numbers attached to a Dirichlet character chi and investigate certain symmetric identities involving the polynomials, by mainly using the theory of p-adic integral on Z(p). The results presented here, being very general, are shown to reduce to yield symmetric identities for many relatively simple polynomials and numbers and some corresponding known symmetric identities.
