... R-module, then we can view M as a right Rop -module, by defining the right action of Rop on M by mr := rm, where the right hand side of this equation is the old left action of R on M . Similarly, any right R-module can be viewed as a left Rop -module. This “op” trick will occasionally be useful for ...

Our idea to prove it consists in combining Theorem 2 with a basic theorem in the theory of complex multiplication which determines the prime ideal decomposition of the Frobenius endomorphism of the abelian variety obtained by reducing an abel ...
