In this paper we reinvestigate the structure of the solution of a well-known
Love’s problem, related to the electrostatic field generated by two circular
coaxial conducting disks, in terms of orthogonal polynomial expansions,
enlightening the role of the recently introduced class of the Lucas–Lehmer
polynomials. Moreover we show that the solution can be expanded more
conveniently with respect to a Riesz basis obtained starting from Chebyshev
polynomials.
