group homomorphism meaning in English

群同态

In some finiteness conditions , we prove that there exists a natural abelian group homomorphism from the grothendieck group of r to the grothendieck group of a . in particular , the homomorphism is splitting if p is quasi - n - tilting
在适当的有限性条件下，我们证明了一个从r的grothendieck群到a的orothendieck群的自然的阿贝尔群同态。
By using the theory of finite fields , the relationship of module operation among difference matrices of a mixed difference matrix is generalized to that of group homomorphism . a new concept of normal mixed difference matrix is proposed . the relationship between normal mixed difference matrix and the construction of orthogonal arrays is discovered
