英文摘要: We discuss the integrable hierarchies that appear in multi-matrix models. They can be envisaged as multi-field representations of the KP hierarchy. We then study the possible reductions of this systems via the Dirac reduction method by suppressing successively one by one part of the fields. We find in this way new integrable hierarchies, of which we are able to write the Lax pair representations by means of suitable Drinfeld-Sokolov linear systems. At the bottom of each reduction procedure we find an Nth KdV hierarchy. We discuss in detail the case which leads to the KdV hierarchy and to the Boussinesque hierarchy, as well as the general case in the dispersionless limit.
