Polylogarithm

WebThe polylogarithm function (or Jonquière's function) of index and argument is a special function, defined in the complex plane for and by analytic continuation otherwise. It can be plotted for complex values ; for example, along the celebrated critical line for Riemann's zeta function [1]. The polylogarithm function appears in the Fermi–Dirac and Bose–Einstein … WebInformally, a cluster polylogarithm is a homotopy-invariant iterated integral ż γ ÿ i “ dlogpai 1q ... dlogpai nq ‰ on XsmpCq where for each ithere exists a cluster containing cluster variables ai 1,...,a i n. We call the latter condition cluster adjacency, it was inspired by [DFG18]. Consider the following simplest example.

In mathematics, Spence's function, or dilogarithm, denoted as Li2(z), is a particular case of the polylogarithm. Two related special functions are referred to as Spence's function, the dilogarithm itself: and its reflection. For z < 1, an infinite series also applies (the integral definition constitutes its analytical extension to the complex plane): WebThis function is defined in analogy with the Riemann zeta function as providing the sum of the alternating series. η ( s) = ∑ k = 0 ∞ ( − 1) k k s = 1 − 1 2 s + 1 3 s − 1 4 s + ….
