spence

In mathematics, Spence's function, or dilogarithm, denoted as Li2(z), is a particular case of the polylogarithm. Lobachevsky's function and Clausen's function are closely related functions. Two related special functions are referred to as Spence's function, the dilogarithm itself, and its reflection with the variable negated.
