| Özet |
| In this paper we investigate the best approximation by trigonometric polynomials in the variable exponent weighted Morrey spaces Mp(⋅),λ(⋅)(I0,w), where w is a weight function in the Muckenhoupt Ap(⋅)(I0) class. We get a characterization of K-functionals in terms of the modulus of smoothness in the spaces Mp(⋅),λ(⋅)(I0,w). Finally, we prove the direct and inverse theorems of approximation by trigonometric polynomials in the spaces Mp(⋅),λ(⋅)(I0,w), the closure of the set of all trigonometric polynomials in Mp(⋅),λ(⋅)(I0,w). |
