Local properties of Fourier series
International Journal of Mathematics and Mathematical Sciences, 2000 A theorem on local property of |N¯,pn|k summability of factored Fourier series, which generalizes some known results, and also a general theorem concerning the |N¯,pn|k summability factors of Fourier series have been proved.

Summabilty of the Fourier-Laplace series in the Nikol’skii spaces
, 2023 In this paper we study convergence and summability problems of the series associated with the Laplace-Beltrami operator on the unique sphere. These series known as Fourier-Laplace series and we study the behaviour of these series in the different spaces ...

Estimates for commutators of orthogonal fourier series [PDF]
, 1996 In this paper we study weighted norm inequalities for the commutators [b, Sn] where b is a BMO function and Sn denotes the nth partial sum of the Fourier series relative to a system of orthogonal polynomials on [-1, 1] with respect to general weights ...

Modified Fourier expansions: theory, construction and applications [PDF]
, 2010 Modified Fourier expansions present an alternative to more standard algorithms for the approximation of nonperiodic functions in bounded domains. This thesis addresses the theory of such expansions, their effective construction and computation, and ...

The surprising almost everywhere convergence of Fourier-Neumann series [PDF]
, 2009 For most orthogonal systems and their corresponding Fourier series, the study of the almost everywhere convergence for functions in Lp requires very complicated research, harder than in the case of the mean convergence.

Reactive loading function on tunnel excavation contour in rock mass [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2003 Investigation of the stress field around the cavity that is loaded or partially loaded at the inner surface by the rotationally symmetric loading is still the contemporary problem in the theory of elasticity.
