摘要：
InthispaperweintroducethenotionofaweakYetter-Drinfeldgroupmodule over a weak T-coalgebra and give some basic properties. Moreover we also prove that the category of weak Yetter-Drinfeld group modules is isomorphic to the center of the representation category of a weak T-coalgebra H denoted by Z(Rep(H)).
