Fibonacci type sequences and integer multiples of periodic continued fractions

We construct a class of quadratic irrationals having continued fractions of period n ≥ 2 with `small’ partial quotients for which specific integer multiples have periodic continued fractions with the length of the period being 1 , 2 or 4 , and with ‘large’ partial quotients. We then show that numbers in the period of the new continued fraction are functions of the numbers in the periods of the original continued fraction. We also show how polynomials arising from generalizations of these continued fractions are related to Chebyshev and Fibonacci polynomials and, in some cases, have hyperbolic root distribution.
