摘　　要：We present a unified method for constructing generalized flag transformations of unitons intoa Lie group G via singular Darboux transformations. These flag transformations provide the possibility toestablish some factorizations for G-unitons.We present a unified method for constructing generalized flag transformations of unitons into a Lie group G via singular Darboux transformations.
