After defining the k-functor F over X, proves that the trivial extension categoty X∝F is also G-graded.
在定义C上k-函子F的基础上,证明了平凡扩张范畴C∝F仍为k上G-分次范畴;当F为X上分次k-函子时,给出了一族范畴同构,即r∈N(G),有(C#G)∝(F#r)(C∝F)r#G。
2.
We investigate the semicommutative properties of those rings under the reduced condition which are more generalized than trivial extensions.
