摘要：
The Lax pair for a derivative nonlinear Schrodinger equation proposed by Chen-Lee-Liu is generalized into matrix form. This gives new types of integrable coupled derivative nonlinear Schrodinger equations. By virtue of a gauge transformation, a new multi-component extension of a derivative nonlinear Schrodinger equation proposed by Kaup-Newell is also obtained. (C) 1999 Elsevier Science B.V.
