Dickson Polynomials, Chebyshev Polynomials, and Some Conjectures of Jeffery
Stefano Barbero · J. Integer Seq. · 2014
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 A185905 . As a result, we obtain a straightforward proof of some conjectures of Jeffery concerning this sequence and other related ones.
