Bohman extremal problem for the Jacobi transform

D. V. Gorbachev, V. I. Ivanov

Tula State University

Abstract: We give a solution to the Bohman extremal problem for nonnegative even entire functions of exponential type that are Jacobi transforms of compactly supported functions. We prove that the extremal function is unique. The Gauss quadrature formula on the half-line over zeros of the Jacobi function is used.

Keywords: hyperbolic weight, Jacobi function, Jacobi transform, Bohman extremal problem, Gauss quadrature formulae.
