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 在適當(dāng)?shù)挠邢扌詶l件下,我們證明了一個(gè)從r的grothendieck群到a的orothendieck群的自然的阿貝爾群同態(tài)。
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 ?利用有限域理論,把不同水平差集矩陣之間的取模運(yùn)算關(guān)系推廣為更加廣泛的群同態(tài)關(guān)系,提出了標(biāo)準(zhǔn)混合差集矩陣的概念,找到了標(biāo)準(zhǔn)混合差集矩陣和混合水西安電子科技大學(xué)博士學(xué)位論文:正交表的構(gòu)造方法及其應(yīng)用平正交表的構(gòu)造之間的關(guān)系,提出了利用標(biāo)準(zhǔn)混合差集矩陣構(gòu)造正交表的方法且構(gòu)造了一些新的正交表
