@inproceedings{Li2020ALT, title={A Liouville theorem for M\"\{o\}bius invariant equations}, author={Yanyan Li and Han-Chun Lu and Siyuan Lu}, year={2020} }
In this paper we classify Möbius invariant differential operators of second order in two dimensional Euclidean space, and establish a Liouville type theorem for general Möbius invariant elliptic equations.
