On the degree of approximation of Fourier series based on a certain class of product deferred summability means
Abstract In this article, we first introduce and study the basic concepts of deferred Euler and deferred Nörlund product summability means of Fourier series of arbitrary periodic functions. We then estimate the degree of approximation of Fourier series of an arbitrary periodic function in the genera...
