Niven’s Algorithm Applied to the Roots of the Companion Polynomial Over $${{\mathbb {R}}}^4$$ R 4 Algebras

Niven’s Algorithm Applied to the Roots of the Companion Polynomial Over $${{\mathbb {R}}}^4$$... This paper will contain an extension of Niven’s algorithm of 1941, which in its original form is designed for finding zeros of unilateral polynomials p over quaternions $${\mathbb {H}}$$ H . The extensions will cover the algebra $${{\mathbb {H}}_{\mathrm{coq}}}$$ H coq of coquaternions, the algebra $${{\mathbb {H}}_{\mathrm{nec}}}$$ H nec of nectarines and the algebra $${{\mathbb {H}}_{\mathrm{con}}}$$ H con of conectarines. These are nondivision algebras in $${{\mathbb {R}}}^4$$ R 4 . In addition, it is also shown that in all algebras the most difficult part of Niven’s algorithm can easily be solved by inserting the roots of the companion polynomial c of p, with the result, that all zeros of all unilateral polynomials over all noncommutative $${{\mathbb {R}}}^4$$ R 4 algebras can be found. In addition, for all four algebras the maximal number of zeros can be given. For the three nondivision algebras besides the known types of zeros: isolated, spherical, hyperbolic, a new type of zero will appear, which will be called unexpected zero of p. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Applied Clifford Algebras Springer Journals
