The skyrmions in SU(N) quantum Hall (QH) system are discussed. By analyzing the gauge field structureand the topological properties of this QH system it is pointed out that in the SU(N) QH system there can exist (N-1)types of skyrmion structures, instead of only one type of skyrmions. In this paper, by means of the Abelian projectionsaccording to the (N-1) Cartan subalgebra local bases, we obtain the (N-1) U(1) e1ectroinagnetic field tensors in theSU(N) gauge field of the QH system, and then derive (N-1) types of skyrmion structures from these U(1) sub-fieldtensors. Furthermore, in light of the ф-mapping topological current method, the topological charges and the motion ofthese skyrmions are also discussed.
