【摘要】 从泊松作用的角度考察了群胚上的半直积结构,定义了泊松群胚对泊松群胚的泊松作用,讨论了其性质,并证明了两个泊松群胚的半直积仍是泊松群胚,从而对群胚的半直积结构有了更多的认识.更多还原

【Abstract】 In this paper,we considered the general semidirect product structure of groupoids in terms of the Poisson actions,defined the Poisson action of one Poisson groupoids to the other,obtained some properties and proved that the general semidirect products of the two Poisson groupoids is also a Poisson groupoids.This allows us to know the general semidirect product structure of groupoids more.更多还原
