Modular Nekrasov-Okounkov Formulas
Using Littlewood's map, which decomposes a partition into its r-core
and r-quotient, Han and Ji have shown that many well-known hook-length
formulas admit modular analogues.
In this paper we present a variant of the Han-Ji `multiplication theorem'
based on a new analogue of Littlewood's decomposition.
We discuss several applications to hook-length formulas, one of which
leads us to conjecture a modular analogue of the q,t-Nekrasov-Okounkov
