Fourier Series for Functions Related to Chebyshev Polynomials of the First Kind and Lucas Polynomials [PDF]

open access: yesMathematics, 2018
In this paper, we derive Fourier series expansions for functions related to sums of finite products of Chebyshev polynomials of the first kind and of Lucas polynomials. From the Fourier series expansions, we are able to express those two kinds of sums of
