CHAPTERS HURWITZ ZETA, LERCH, POLYLOGS AND DIRICHLET BETA

            In this entry I´ll share the draft of some chapters of my ongoing personal project of writing a book. The chapters here serve as a reference for the Hurwitz Zeta function, Lerch Transcedental, Polylogarithms and the Dirichlet Beta function which knowledge will be used in future chapters to solve actual problems (series, integrals and products). I´ve tried to use as elementary tools as possible, but in some instances some complex analysis, in particular contour integration was unavoidable.

JACOBI TRIPLE PRODUCT AND PRODUCT REPRESENTATION OF JACOBI THETA FUNCTIONS

In this entry I will prove the remarkable Jacobi triple product using one of the most elementary proofs due to great mathematician George Andrews. Additionally, it will be shown some product representations of Jacobi theta function and the beautiful Euler´s pentagonal theorem This note is an excerpt of my ongoing personal project of putting all the blog content with additional content in a book format, so if you like it or would like to leave a comment please let me know.
