Singular moduli of higher level and special cycles

Abstract

We describe the complex multiplication (CM) values of modular functions for Γ0(N)\Gamma_0(N) whose divisor is given by a linear combination of Heegner divisors in terms of special cycles on the stack of CM elliptic curves. In particular, our results apply to Borcherds products of weight 00 for Γ0(N)\Gamma_0(N). By working out explicit formulas for the special cycles, we obtain the prime ideal factorizations of such CM values.
