Eta Products

Abstract

By an eta product we understand any finite product of functions
$$f(z) = \prod_{m} \eta(mz)^{a_m}$$
where m runs through a finite set of positive integers and the exponents a m may take any values from ℤ, positive or negative or 0. (Of course, an exponent 0 contributes a trivial factor 1 to the product, and therefore we may as well assume that a m ≠0 for all m.) Since the product is finite, the lowest common multiple N=lcm {m} exists, and every m divides N.
