We prove that the coefficients of certain weight− 1/2 harmonic Maass forms are “traces” of singular moduli for weak Maass forms. To prove this theorem, we construct a theta lift from spaces of weight− 2 harmonic weak Maass forms to spaces of weight− 1/2 vector-valued harmonic weak Maass forms on Mp 2 (Z), a result which is of independent interest. We then prove a general theorem which guarantees (with bounded denominator) when such Maass singular moduli are algebraic. As an example of these results, we derive a formula for the partition function p (n) as a finite sum of algebraic numbers which lie in the usual discriminant− 24 n+ 1 ring class field.
