Abstract
In this paper we present a geometric way to extend the Shintani lift from even weight cusp forms for congruence subgroups to arbitrary modular forms, in particular Eisenstein series. This is part of our eorts to extend in the noncompact situation the results of Kudla-Millson and Funke-Millson relating Fourier coecients of (Siegel) modular forms with intersection numbers of cycles (with coe cients) on orthogonal locally symmetric spaces. In the present paper, the cycles in question are the classical modular symbols with nontrivial coecients. We introduce \capped" modular symbols with coecients which we call \spectacle cycles" and show that the generating series of cohomological periods of any modular form over the spectacle cycles is a modular form of half-integral weight.
