Abstract: 

Conformally invariant equations in n\geq3 have played an important role in the study of \sigma_k-Yamabe problem in geometric analysis. In this talk, we will discuss a class of Mobius invariant equations in dimension two and then present a Liouville type theorem for such equations. We will then discuss the \sigma_2-Nirenberg problem on \mathbb{S}^2. This is based on joint works with Yanyan Li and Han Lu.
