EICHLER COHOMOLOGY THEOREM FOR GENERALIZED MODULAR FORMS.

We show starting with relations between Fourier coefficients of weakly parabolic generalized modular forms of negative weight that we can construct automorphic integrals for large integer weights. We finally prove an Eichler isomorphism theorem for weakly parabolic generalized modular forms using the classical approach as in [3]. [ABSTRACT FROM AUTHOR]
