摘要：

Continuum Virasoro constraints in the two-cut hermitian matrix models are derived from the discrete Ward identities by means of the mapping from the GL(infinity) Toda hierarchy to the nonlinear Schrodinger (NLS) hierarchy. The invariance of the string equation under the NLS flows is worked out. Also the quantization of the integration constant alpha reported by Hollowood et al. is explained by the analyticity of the continuum limit.
