Fourier's Series [PDF]

open access: yesNature, 1899
THE difficulty referred to by Prof. Michelson in NATURE of October 6, 1898, and in subsequent letters, to that in your issue of January 19, involves a disregard of the distinction which it is necessary to make between a quantity which, however small it may at first be taken, is thereafter to be kept fixed, and a quantity which can be or is absolutely ...

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

open access: yes, 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.

Reactive loading function on tunnel excavation contour in rock mass [PDF]

open access: yesFacta 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.

Wave fronts via Fourier series coefficients [PDF]

open access: yes, 2015
Motivated by the product of periodic distributions, we give a new description of the wave front and the Sobolev-type wave front of a distribution $f\in\mathscr{D}'(\mathbb{R}^d)$ in terms of Fourier series coefficients.Comment: 10 ...

Fourier Series Approximation in Besov Spaces

open access: yesJournal 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.

An algorithm for the machine calculation of complex Fourier series

open access: yes, 1965
An efficient method for the calculation of the interactions of a 2' factorial ex- periment was introduced by Yates and is widely known by his name. The generaliza- tion to 3' was given by Box et al. (1).
