对于相对Hopf模,定义了一种新的代数非交换微分形式,并且得出了相对Hopf模与在某一微分上具有平坦联络的模之间有一一对应的关系.
In the paper, a new algebra of noncommutative differential forms for Hopf modules is defined. It is shown that there is a one to one correspondence between Hopf modules, and modules Which admit a flat connection with respect to the differential calculus.
