Dirichlet beta function
From Wikipedia, the free encyclopedia
This article is about the Dirichlet beta function. For other beta functions, see Beta function (disambiguation).
In mathematics, the Dirichlet beta function (also known as the Catalan beta function) is a special function, closely related to the Riemann zeta function. It is a particular Dirichlet L-function, the L-function for the alternating character of period four.
