Special functions and orthogonal polynomials in particular have been around for centuries. In the twentieth century the emphasis was on special functions satisfying linear differential equations, but this has been extended to difference equations, partial differential equations and non-linear differential equations.
This special issue will reflect the interplay of difference/differential equations, special functions and polynomials.
