| dc.description | We can write the polynomial solution of the second order linear differential equation of hypergeometric-type $$ ϕ(x)y''+ψ(x)y'+λy=0, $$ where $ϕ$ and $ψ$ are polynomials, $°ϕ\le 2$, $°ψ=1$ and $λ$ is a constant, among others, by using the Rodrigues operator $R_k(ϕ,{\bf u})$ (see \cite{coma2}) where $\bf u$ is certain linear operator which satisfies the distributional equation \begin{equation} \label{1} \frac{d}{dx}[ϕ{\bf u}]=ψ{\bf u}, \end{equation} as $$ P_n(x)=B_n R_n(ϕ,{\bf u})[1], \qquad B_n\ne 0,\quad n=0, 1, 2, ... $$ Taking this into account we construct the complementary polynomials. Among the key results is a generating functional function in closed form leading to derivations of recursion relations and addition theorem. The complementary polynomials satisfy a hypergeometric-type differential equation themselves, have a three-term recursion among others and Rodrigues formulas. | |
