New Factor Pairs for Factorizations of Lambert Series Generating Functions

Abstract: We prove several new variants of the Lambert series factorization theorem established in the first article "Generating special arithmetic functions by Lambert series factorizations" by Merca and Schmidt (2017). Several characteristic examples of our new results are presented in the article to motivate the formulations of the generalized factorization theorems. Applications of these new factorization results include new identities involving the Euler partition function and the generalized sum-of-divisors functions, the M\"obius function, Euler's totient function, the Liouville lambda function, von Mangoldt's lambda function, and the Jordan totient function.
