Here we consider complex manifolds M which are holomorphically separable, i.e., the global holomorphic functions (9 (M) separate the points of M. We investigate T n (n-torus) actions on M, where T"={(ei~ ei~ 0eN"}, and n is the complex dimension of M. We assume that the action is effective, i.e., if 0ET ~ is nonzero, then there exists z e M with O.z+z. Our final assumption on the action is one of smoothness; the map T n x M ~ M given by (0, z ) , O . z is C 1 in both variables and holomorphic in z. The most obvious examples of such actions are given by Reinhardt domains in ~", with the usual action O.z=(ei~ . . . . , e i ~ The standard Reinhardt action may also be changed as follows: if A is an algebraic automorphism of T n, then O.az=(AO).z. An obvious question that arises is whether all T"-actions can arise in this way. Our main results are contained in the following four theorems.
