Invitation to q-series, an: from jacobi's triple product identity to ramanujan's "most beautiful identity" (World Scientific Publishing Co Pte Ltd)

The aim of this lecture notes is to provide a self-contained exposition of several fascinating formulas discovered żeby Srinivasa Ramanujan. Two central results in these notes are: the evaluation of the Rogers-Ramanujan continued fraction - a result that convinced G.H. Hardy that Ramanujan was a mathematician of the 'highest class', and what G.H. Hardy called Ramanujan's 'Most Beautiful Identity'. This book covers a range of related results, such as several proofs of the famous Rogers-Ramanujan identities and a detailed account of Ramanujan's congruences. It also covers a range of techniques in q-series.
