Fourier coefficients of an almost-periodic function
From Encyclopedia of Mathematics
The coefficients 
of the Fourier series (cf. Fourier series of an almost-periodic function) corresponding to the given almost-periodic function 
:
 |
where
 |
The coefficients 
are completely determined by the theorem on the existence of the mean value
 |
which is non-zero only for the countable set of values 
.
