Abstract
This paper gets the Beltrami equations satisfied by a 1-quasiconformal mapping, which are exactly CR or anti-CR equations on (2,2)-type quadric Q 0. This means a 1-quasiconformal mapping on Q 0 is CR or anti-CR. This reduces the determination of 1-quasiconformal mappings to a problem on the theory of several complex analysis. The result about the group of CR automorphisms is used to determine the unit component of group of 1-quasiconformal mappings.
