Matrix Summability of Walsh–Fourier Series

Mathematics, 2022
The presented paper discusses the matrix summability of the Walsh–Fourier series. In particular, we discuss the convergence of matrix transforms in L1 space and in CW space in terms of modulus of continuity and matrix transform variation.

Quantization of pseudo-differential operators on the torus [PDF]

, 2008
Pseudo-differential and Fourier series operators on the n-torus are analyzed by using global representations by Fourier series instead of local representations in coordinate charts.

Vector valued formal Fourier-Jacobi series [PDF]

, 2014
H. Aoki showed that any symmetric formal Fourier-Jacobi series for the symplectic group Sp_2(Z) is the Fourier-Jacobi expansion of a holomorphic Siegel modular form.

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.

Lacunary Fourier series and a qualitative uncertainty principle for compact Lie groups [PDF]

, 2010
We define lacunary Fourier series on a compact connected semisimple Lie group $G$. If $f \in L^1(G)$ has lacunary Fourier series, and vanishes on a non empty open set, then we prove that $f$ vanishes identically.

Fourier Series Approximation in Besov Spaces

Journal of Mathematics, 2023
Defined on the top of classical Lp-spaces, the Besov spaces of periodic functions are good at encoding the smoothness properties of their elements.

Fractional Derivative as Fractional Power of Derivative [PDF]

, 2007
Definitions of fractional derivatives as fractional powers of derivative operators are suggested. The Taylor series and Fourier series are used to define fractional power of self-adjoint derivative operator.
