Dirichlet Series

A series


where a(n) and z are complex and {lambda(n)} is a monotonic increasing sequence of real numbers. The numbers lambda(n) are called the exponents, and a(n) are called the coefficients. When lambda(n)=lnn, then e^(-lambda(n)z)=n^(-z), the series is a normal Dirichlet L-series. The Dirichlet series is a special case of the Laplace-Stieltjes transform.
