Comments on the height reducing property
A complex number α is said to satisfy the height reducing property if there is a finite subset, say F, of the ring ℤ of the rational integers such that ℤ[α] = F[α]. This property has been considered by several authors, especially in contexts related to self affine tilings and expansions of real numbers in non-integer bases. We prove that a number satisfying the height reducing property, is an algebraic number whose conjugates, over the field of the rationals, are all of modulus one, or all of modulus...

Criterion of the reality of zeros in a polynomial sequence satisfying a three-term recurrence relation
This paper establishes the necessary and sufficient conditions for the reality of all the zeros in a polynomial sequence generated by a three-term recurrence relation with the standard initial conditions where and are arbitrary real polynomials.
