Query: The Lie algebra of sl(2)-valued automorphic functions on a torus   It is shown that the Lie algebra of the automorphic, meromorphic sl(2, C)
-valued functions on a torus is a geometric realization of a certain
infinite-dimensional finitely generated Lie algebra. In the trigonometric
limit, when the modular parameter of the torus goes to zero, the former Lie
algebra goes over into the sl(2,C) -valued loop algebra, while the latter one -
into the Lie algebra (sl(2)^)'/(centre) .
