Jackson and Stechkin type inequalities of trigonometric approximation in A(w,v)(p,q)((.))
Avşar, Ahmet Hamdi; Koç, Hüseyin (Scientific Technical Research Council Turkey-TUBITAK, 2018)In this paper, we study Jackson and Stechkin type theorems of trigonometric polynomial approximation in the space A(w,v)(p,q(.)) by considering a modulus of smoothness defined by virtue of the Steklov operator. -
On trigonometric approximation in weighted lorentz spaces using norlund and riesz submethods
