He also provides a grounding in the theory of classical modular forms, starting with modular forms for SL2(Z), and progressing to modular forms of higher level, modular functions,

half-integral weight modular forms, and mod p modular forms.

Finite-dimensional irreducible representations of the classical type of the algebra [U.sub.q] (so (5)) are given by two integral or

half-integral numbers [n.sub.1] and [n.sub.2], such that [n.sub.1] [greater than or equal to] n2 [greater than or equal to] 0.

The [eta]-multiplier system and the integer powers of them are multiplier systems for all

half-integral weights [8].
