Solution of a quadratic quaternion equation with mixed coefficients
A comprehensive analysis of the morphology of the solution space for a
special type of quadratic quaternion equation is presented. This equation,
which arises in a surface construction problem, incorporates linear terms in a
quaternion variable and its conjugate with right and left quaternion
coefficients, while the quadratic term has a quaternion coefficient placed
between the variable and its conjugate. It is proved that, for generic
coefficients, the equation has two, one, or no solutions, but in certain
special instances the solution set may comprise a circle or a 3-sphere in the
quaternion space . The analysis yields solutions for each case, and
intuitive interpretations of them in terms of the four-dimensional geometry of
the quaternion space .Comment: 19 pages, to appear in the Journal of Symbolic Computatio
Quadratic Equation over Associative D-Algebra
In this paper, I treat quadratic equation over associative -algebra. In
quaternion algebra , the equation has either roots, or
infinitely many roots. Since , , then the equation has infinitely
many roots. Otherwise, the equation has roots , , . I
considered different forms of the Viete's theorem and a possibility to apply
the method of completing the square.
In quaternion algebra, there exists quadratic equation which either has
root, or has no roots.Comment: English text - 34 pages; Russian text - 35 page
Solvability of Equations in Clifford Algebras
University of Minnesota M.S. thesis. October 2016. Major: Applied and Computational Mathematics. Advisor: Joseph Gallian. 1 computer file (PDF); vii, 71 pages.In this paper, we are studying selected types of quadratic equations in Clifford algebra, using methods developed for solving analogous equations in quaternions. Our goal is to classify the solutions in order to build a solid foundation for the study of Minkowski Pythagorean hodograph curves
