Let g denote the Virasoro Lie algebra, h its Cartan subalgebra, and S(h) the symmetric algebra on h. In this paper we consider "thickened" Verma modules M(Ξ») which are (U (g), S(h))-bimodules satisfying M(Ξ») β S(h) C βΌ = M(Ξ») where M(Ξ») is the usual Verma module with highest weight Ξ» β h \* . We det
