Monogenic period equations are cyclotomic polynomials
We study monogeneity in period equations, psi(e)(x), the auxiliary equations introduced by Gauss to solve cyclotomic polynomials by radicals. All monogenic psi(e)(x) of degrees 4 = 4, we conjecture all monogenic period equations to be cyclotomic polynomials. Totally real period equations are of interest in applications of quadratic discrete-time dynamical systems

In this paper, we provide some explicit conditions only on and for

for which divides the index of . As an application of our results, we
provide some infinite parametric families of number fields which are

Polynomial Roots and Calabi-Yau Geometries
The examination of roots of constrained polynomials dates back at least to
Waring and to Littlewood. However, such delicate structures as fractals and
holes have only recently been found. We study the space of roots to certain
integer polynomials arising naturally in the context of Calabi-Yau spaces,
notably Poincare and Newton polynomials, and observe various salient features
and geometrical patterns.Comment: 22 pages, 13 Figure
