Mathematicians are still trying to understand fundamental properties of the Fourier transform, one of their most ubiquitous ...

Joseph Fourier was a French mathematician, born on 21 March 1768 in Auxerre, France. His name is closely associated with the Fourier series and Fourier transform, mathematical tools utilised in a wide ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

This is a preview. Log in through your library . Abstract We study the accuracy of the output of the Fast Fourier Transform by estimating the expected value and the variance of the accompanying linear ...

This paper introduces a method for the analysis of differential equations with polynomial coefficients which also provides a further insight for the Stokes phenomenon. This method consists of a chain ...
