Hecke relations among 2d fermionic RCFTs
A bstract Recently, Harvey and Wu proposed a suitable Hecke operator for vector-valued SL(2, ℤ ) modular forms to connect the characters of different 2d rational conformal field theories (RCFTs). We generalize such an operator to the 2d fermionic RCFTs and call it fermionic Hecke operator . The new Hecke …
