چکیده

We investigate the class of ±1 polynomials evaluated at q defined as: A(q) = { 0 + 1q + · · · + mq : i ∈ {−1, 1}} and usually called spectrum, and show that, if q is the root of the polynomial xn − xn−1 − · · · − xk+1 + xk + xk−1 + · · · + x + 1 between 1 and 2, and n > 2k + 3, then A(q) is discrete, which means that it does not have any accumulation points.

Numbers , Pisot Numbers , Mahler Measure and Graphs

We use graphs to define sets of Salem and Pisot numbers, and prove that the union of these sets is closed, supporting a conjecture of Boyd that the set of all Salem and Pisot numbers is closed. We find all trees that define Salem numbers. We show that for all integers n the smallest known element of the n-th derived set of the set of Pisot numbers comes from a graph. We define the Mahler measur...

Some computations on the spectra of Pisot and Salem numbers

Properties of Pisot numbers have long been of interest. One line of questioning, initiated by Erdős, Joó and Komornik in 1990, is the determination of l(q) for Pisot numbers q, where l(q) = inf(|y| : y = 0 + 1q + · · ·+ nq, i ∈ {±1, 0}, y 6= 0). Although the quantity l(q) is known for some Pisot numbers q, there has been no general method for computing l(q). This paper gives such an algorithm. ...

Non-trivial Quadratic Approximations to Zero of a Family of Cubic Pisot Numbers

This paper gives exact rates of quadratic approximations to an infinite class of cubic Pisot numbers. We show that for any cubic Pisot number q, with minimal polynomial p, such that p(0) = −1, and where p has only one real root, then there exists a C(q), explicitly given here, such that: (1) For all > 0, all but finitely many integer quadratics P satisfy |P (q)| ≥ C(q)− H(P )2 where H is the he...

Tilings from some non-irreducible, Pisot substitutions

A generating method of self-affine tilings for Pisot, unimodular, irreducible substitutions, as well as the fact that the associated substitution dynamical systems are isomorphic to rotations on the torus are established in [AI01]. The aim of this paper is to extend these facts in the case where the characteristic polynomial of a substitution is non-irreducible for a special class of substituti...
