Trigonometric approximation of periodic functions in Morrey spaces using matrix means of their Fourier series


Sadulla Z. Jafarov




We examine the generalized methods of summability of Fourier series of functions belonging to Morrey spaces $L^{p,\lambda}$, $0<\lambda \leq 2$, $1<p<\infty $. In this study, the approximation of functions by matrix means in terms of the continuity modulus in Morrey spaces $L^{p,\lambda}$, $0<\lambda \leq 2$, $1<p<\infty$, is investigated.
