摘要：
We derive the Schwinger-Dyson loop equations for the multi-matrix chain models at finite N, from the Ward identities of the partition function under the infinitesimal field transformations. The constraint operators W(n)(m) satisfy the w1+infinity-like algebra up to a linear combination of the lower spin operators. We find that all the higher spin constraints are reducible to the Virasoro-type constraints for all the matrix chain models.
