Every non-zero complex homomorphism of the almost periodic functions on an abelian group is induced by the Fourier transform. A Plancherel formula for almost periodic functions and a necessary ...
The Canadian Journal of Statistics / La Revue Canadienne de Statistique Using Fourier series expansions of functions of one and two variables, we find the variances of the sample mean for random and ...
Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...
