A. Acus, A. Dargys

AI总结:

该研究提出了3维及以下实Clifford代数中多重向量的根式平方根算法,明确了不同Clifford代数中孤立根的最大数量及连续根的存在情况,并辅以示例说明。

摘要:

本文提出了一种在n=p+q≤3的实Clifford代数Cl(p,q)中,用根式提取多重向量(MV)平方根的算法。我们证明,在Cl(3,0)、Cl(1,2)和Cl(0,3)代数中,最一般的(泛型)多重向量最多存在4个孤立根。Cl(2,1)代数是个例外,其中的多重向量最多可拥有16个孤立根。除孤立根外,除p+q=1的情况外,所有代数中都可能出现连续根族。文中还提供了若干示例,阐释n=3的Clifford代数中可能出现的各类根的性质。

英文摘要:

An algorithm to extract the square root in radicals from a multivector (MV) in real Clifford algebras Cl(p,q) for n=p+q <=3 is presented. We show that in the algebras Cl(3,0), Cl(1,2) and Cl(0,3) there are up to four isolated roots in a case of the most general (generic) MV. The algebra Cl(2,1) makes up an exception and the MV here can have up to 16 isolated roots. In addition to isolated roots, a continuum of roots can appear in all algebras except p+q=1. A number of examples are provided to illustrate properties of various roots that may appear in n=3 Clifford algebras.
