Growth and Chebyshev Approximation of Entire Function Solution of Helmholtz Equation in R2

Devendra Kumar

Abstract

Some bounds on growth parameters of entire function solutions of Helmholtz equation in

R2 have been studied in terms of Chebyshev polynomial approximation error in sup norm.Our results extend and improve the results studied by McCoy[9].

Keywords

Chebyshev approximation, growth parameter Bergman integral
