Dickson polynomials, Chebyshev polynomials, and some conjectures of Jeffery
J. Integer Seq. 17(3), Article 14.3.8, 6 p., electronic only (2014)
Summary
Summary: By using Dickson polynomials in several variables and Chebyshev polynomials of the second kind, we derive the explicit expression of the entries in the array defining the sequence A185095. As a result, we obtain a straightforward proof of some conjectures of Jeffery concerning this sequence and other related ones.
