Different aspects of harmonic analysis, complex analysis, sampling theory, approximation theory and related topics are covered
in this volume. The topics included are Fourier analysis, Pade approximation, dynamical systems and difference operators,
splines, Christoffel functions, best approximation, discrepancy theory and Jackson-type theorems of approximation. The articles
of this collection were originated from the International Conference in Approximation Theory, held in Savannah, GA in 2017,
and organized by the editors of this volume.
