摘要
The infinite-dimensional algebras on two-dimensional torus are developed.In particular the diffeomorphism algebra and the Beltrami algebra on torus with their central extensions have been presented.It is shown that these algebras are corresponding to the diffeomorphism and the quasiconformal transformation of torus,respectively.
