Finite quadratic modules and lattices

Xiao-Jie Zhu

We give a new proof of the fact that any finite quadratic module can be decomposed into indecomposable ones. For any indecomposable finite quadratic module, we construct a lattice,…

Double coset operators and eta-quotients

Hai-Gang Zhou, Xiao-Jie Zhu

We study a type of generalized double coset operators which may change the characters of modular forms. For any pair of characters $v_{1}$ and $v_{2}$ , we describe explicitly those ope…
