A $q$-linear analogue of the plane wave expansion [PDF]
Luís Daniel Abreu, Óscar Ciaurri, Juan Luis VaronaWe obtain a $q$-linear analogue of Gegenbauer's expansion of the plane wave. It is expanded in terms of the little $q$-Gegenbauer polynomials and the \textit{third} Jackson $q$-Bessel function. The result is obtained by using a method based on bilinear biorthogonal expansions.View original: http://arxiv.org/abs/1211.0739
