摘要：

A systematic method is presented to obtain a large class of constraint equations for matrix models at finite N. These constraints are associated with the higher order differential operators with respect to the eigenvalues of the matrices, {{lambda-n partial lambda-m}} with n, m greater-than-or-equal-to 0. In the case of the one-matrix model, we find that the constraints for lower m are reducible to the Virasoro constraints. We derive a class of new constraint equations for the matrix chains.
