| contents | An electrostatic model is presented to describe the behaviour of the roots of classical discrete orthogonal polynomials. Indeed, this model applies in the more general frame of polynomial solutions of second-order linear difference equations $$AΔ_h\nabla_h y+BΔ_h y+ C y=0\,,$$ where $A$, $B$ and $C$ are polynomials and $$Δ_h f(x)=f(x+h)-f(x)\qquad \text{ and }\qquad \nabla_h f(x)=f(x)-f(x-h)$$
with $h>0$. |
