Irreducibility of a holomorphic eta quotient is determinable
arXiv:1602.03087
Abstract
We show that a holomorphic eta quotient has only finitely many factors. We also provide an algorithm for checking irreducibility of holomorphic eta quotients by constructing an upper bound for the minimum of the levels of the proper factors of a reducible holomorphic eta quotient.
There are several errors in the paper: In Section 2, the statements of Theorem 2, Corollary 7 and Lemma 2 are not entirely correct. In Section 6, there are mistakes in the proof of Lemma 7
