Fourier-Bessel series
From Encyclopedia of Mathematics
The expansion of a function 
in a series
 | (*) |
where 
is a function given on the interval 
, 
is the Bessel function of order 
(cf. Bessel functions), and the 
are the positive zeros of 
taken in increasing order; the coefficients 
have the following values:

If 
is a piecewise-continuous function given on an interval 
and if the integral

then the Fourier–Bessel series converges and its sum is equal to 
at each interior point 
of 
at which 
locally has bounded variation.
