R-equivariant Form of the Berezin Quantization of the Upper Half Plane

Defines the $\Gamma$ equivariant form of Berezin quantization, where $\Gamma$ is a discrete lattice in $PSL(2, \mathbb R)$. The $\Gamma$ equivariant form of the quantization corresponds to a deformation of the space $\mathbb H/\Gamma$ ($\mathbb H$ being the upper halfplane).
