低维(n=p+q<3)Clifford代数中多重向量的指数和对数

Exponential and logarithm of multivector in low dimensional (n=p+q<3) Clifford algebras

Adolfas Dargys, Arturas Acus

摘要:

在实Clifford几何代数Cl(p,q)中,当n=p+q=1(复数和双曲数)和n=2(Hamilton、分裂和锥心四元数)时,给出了多向量指数和对数的封闭形式表达式.从基向量的平方为-1或+1的Cl(0,1)和Cl(1,0)代数出发,将指数公式和对数公式推广到二维四元数代数Cl(0,2),Cl(1,1)和Cl(2,0).在多向量系数空间中找到二维对数存在的扇区,它们与多向量的平方根有关。

英文摘要:

Closed form expressions for a multivector exponential and logarithm are presented in real Clifford geometric algebras Cl(p,q)when n=p+q=1 (complex and hyperbolic numbers) and n=2 (Hamilton, split and conectorine quaternions). Starting from Cl(0,1) and Cl(1,0) algebras wherein square of a basis vector is either -1 or +1, we have generalized exponential and logarithm formulas to 2D quaternionic algebras, Cl(0,2), Cl(1,1), and Cl(2,0). The sectors in the multivector coefficient space where 2D logarithm exists are found. They are related with a square root of the multivector.
