Mock modular Mathieu moonshine modules
Mock modular Mathieu moonshine modules
We construct super vertex operator algebras which lead to modules for moonshine relations connecting the four smaller sporadic simple Mathieu groups with distinguished mock modular forms. Starting with an orbifold of a free fermion theory, any subgroup of $$\textit{Co}_0$$ that fixes a 3-dimensional subspace of its unique non-trivial 24-dimensional representation …
