Some integrals of gamma, polygamma and volterra functions

Infinite integrals of the gamma and polygamma functions are expressed in terms of the Volterra and related functions using the Laplace transformation method. A number of infinite, convolution, indefinite and definite integrals of v(x), v(x, α), μ(x, β) and μ(x, β, α) has been evaluated. A short table of the Volterra function v(x) in the range 0 ≤ x ≤ 10-0 is presented.
