May 21, 2012 at 20:26 comment added Hugo Chapdelaine In fact in order to get the modular invariance you need to throw in an non-holomorphic term like $\frac{C}{y}$ where $y=\Im(z)$.

May 21, 2012 at 20:18 comment added Hugo Chapdelaine You are right there is a missing correcting factor that I need.
May 21, 2012 at 18:29 comment added Victor Protsak There are no modular forms of weight 2 for the full modular group! The ring of modular forms is generated by the Eisenstein series of weight 4 and 6 (see, for example, Serre, "A course in arithmetic").
