Many special cases of
-series arise in the theory of partitions, a topic
treated in §§27.14(i) and 26.9. In Lie algebras
Lepowsky and Milne (1978) and Lepowsky and Wilson (1982) laid foundations
for extensive interaction with
-series. These and other applications are
described in the surveys Andrews (1974, 1986).
More recent applications are given in Gasper and Rahman (2004, Chapter 8) and
Fine (1988, Chapters 1 and 2).
