Gamma Function  Bessel Function Identity
Posted:

I have observed and proved the following identity for all x\ne 0 : $$ (I_{k1}(x) +I_{k+1}(x) )I_{k}(x) (I_{k1}(x)+I_{k+1}(x))I_k(x) = \frac{4 k}{x \Gamma (1k) \Gamma (1+k)} $$
Is this wellknown or trivially derived? Any comments will be appreciated. Thanks, Kerry M. Soileau
