【摘要】We present integral-type Darboux transformation for the mKdV hierarchy and for the mKdV hierarchy with self-consistent sources,In contrast tiwh the nomal Darboux transformation,the integral-type Darboux transformations can offer non-auto-Baecklund transformation between two(2n+1)-th mKdV equations with self-consistent sources with different degrees.This kind of Darboux transformation enables us to construct the N-soliton solution for the mKdV hierarchy with self-consistent sources.We also propose the formulas for the m times repeated integral-type Darboux transformations for both mKdV hierarchy and mKdV hierarchy with self-consistent sources. 【总页数】8页(P.641-648)
