An analysis of the convergence problem of a function in Sobolev and generalized Zygmund norms using product operator

Abstract In this paper, we delve into the convergence challenges concerning a function f represented as a Fourier series within Sobolev and generalized Zygmund norms. Our approach involves utilizing the deferred Nörlund–deferred Cesàro product ( D h μ d μ ( N p , q ) D g μ h μ ( C ) $D_{h_{\mu}}^{d_...
