# Jackson and Stechkin type inequalities of trigonometric approximation in A p,q(·) w,ϑ

Öz In this paper, we study Jackson and Stechkin type theorems of trigonometric polynomial approximation in the space $A_{w,\vartheta }^{p,q(\cdot )}$ by considering a modulus of smoothness defined by virtue of the Steklov operator.
Anahtar Kelimeler:
