四元数和八元数正则函数的零点:除法引理和凸轮轴效应

Zeros of regular functions of quaternionic and octonionic variable: a division lemma and the camshaft effect

Riccardo Ghiloni, Alessandro Perotti

摘要:

详细研究了四元数或八元数变量的正则函数的零点集。利用收敛幂级数的一个除法引理,得到了两个八元数正则函数的零点与其乘积的零点之间的精确关系。在八元数多项式的情形下,得到了代数代数基本定理的一个强形式。我们证明了零点的重数之和等于多项式的次数,并得到了线性多项式的一个因式分解。

英文摘要:

We study in detail the zero set of a regular function of a quaternionic or octonionic variable. By means of a division lemma for convergent power series, we find the exact relation existing between the zeros of two octonionic regular functions and those of their product. In the case of octonionic polynomials, we get a strong form of the fundamental theorem of algebra. We prove that the sum of the multiplicities of zeros equals the degree of the polynomial and obtain a factorization in linear polynomials.
