Abstract
Let p be a prime and f(z)=∑ n a(n)q n be a weakly holomorphic modular function for \(\varGamma _{0}^{*}(p^{2})\) with a(0)=0. We use Bruinier and Funke’s work to find the generating series of modular traces of f(z) as Jacobi forms. And as an application we construct Borcherds products related to the Hauptmoduln \(j_{p^{2}}^{*}\) for genus zero groups \(\varGamma _{0}^{*}(p^{2})\).
