We give fermionic formulas for the characters of induced modules and coinvariants with respect to different subalgebras calculated in the irreducible modules. The characters of coinvariants give multiplicities of projective modules in fusion of induced modules.LaTeX 17 pages, several citations addedQuantum AlgebraMathematical Physicstext
