A universal deformation formula for Connes-Moscovici's Hopf algebra without any projective structure
Xiang Tang, Yijun Yao
We construct a universal deformation formula for Connes-Moscovici's Hopf algebra without any projective structure using Fedosov's quantization of symplectic diffeomorphisms.

Rankin-Cohen Deformations and Representation Theory
Yi-Jun Yao
In this paper, we use the unitary representation theory of to understand the Rankin-Cohen brackets for modular forms. Then we use this interpretation to study the…
