The expansions have asymptotic properties for large values of the degree. The expansions are given in terms of functions that are special cases of the given polynomials. The method is based on expanding integrals in one or two points of the complex plane, these points being saddle points of the phase functions of the integrands.19 p.application/pdfeng© 2004 The Royal Society of EdinburghCharlier polynomialsLaguerre polynomialsJacobi polynomialsConvergent expansionsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
