On Strong Approximation in Generalized Hölder and Zygmund Spaces

B Singh, U Singh - Computer Sciences & Mathematics Forum, 2023 - mdpi.com
The strong approximation of a function is a useful tool to analyze the convergence of its
Fourier series. It is based on the summability techniques. However, unlike matrix …

[PDF][PDF] A certain studies on Norlund summability of series

SK Sahani, LN Mishra - Journal of Linear and Topological Algebra, 2020 - journals.iau.ir
