摘要：

The current algebra of classical non-linear sigma models on arbitrary Riemannian manifolds is analyzed. It is found that introducing, in addition to the Noether current j(mu) associated with the global symmetry of the theory, a composite scalar field j, the algebra closes under Poisson brackets.
