Title: | Approximation by Trigonometric Polynomials in Rearrangement Invariant Quasi Banach Function Spaces | Authors: | Jafarov, Sadulla Z. | Keywords: | best approximation Moduli of smoothness rearrangement invariant quasi Banach function space rearrangement invariant spaces trigonometric approximation |
Publisher: | Birkhauser Verlag AG | Abstract: | We investigate the approximation properties of trigonometric polynomials in rearrangement invariant quasi Banach function spaces. Relations between moduli of smoothness of the derivatives of a functions and those of the functions itself are studied. We prove a theorem on the relationship between the modulus of smoothness and the best approximation in rearrangement invariant quasi Banach function spaces. © 2014, Springer Basel. | URI: | https://hdl.handle.net/11499/7718 https://doi.org/10.1007/s00009-014-0389-y |
