Talk:Fourier–Bessel series

I've corrected the expression for the weight. The denominator must be evaluated with the Bessel in b, not in 0, according to the given definition. — Preceding unsigned comment added by 77.230.59.181 (talk) 17:43, 12 September 2012 (UTC)

It should be stated (in the definition?) that the space spanned by this expansion has a fixed boundary condition $f(b)=0$ (may also state that it also has finite $f(0)$. If you allow $f(0)\rightarrow \infty$ then you will also have to include Neumann functions in the expansion). --AmitAronovitch (talk) 06:15, 9 May 2013 (UTC)

Shouldn't the denominator in the expression for $c_{n}$ have a $J_{\alpha +1}(u_{\alpha ,n})$ as opposed to the $J_{\alpha +1}(u_{\alpha +1,n})$ that it currently shows? If I'm not wrong, the denominator blows up as it currently stands. Praveenv253 (talk) 07:59, 13 May 2013 (UTC)

Assuming expansion in the interval (0,1) where b=1, the denominator of $c_{n}$ seems inconsistent with Mathworld Fourier-Bessel Series, and results seem to diverge when using the formula defined here whereas they seem to converge when using the formula defined at Mathworld, but perhaps this is an error or misinterpretation on my part.
