    La relación de recurrencia para la función Bessel de orden general ahora se\(\pm\nu\) puede resolver usando la función gamma,

    \[a_{m} = -\frac{1}{m(m\pm 2\nu)} a_{m-2} \nonumber \]

    tiene las soluciones (\(x > 0\))

    \[\begin{aligned} J_{\nu}(x) &= \sum_{k=0}^{\infty}\frac{(-1)^{k}}{k!\Gamma(\nu+k+1)} \left(\frac{x}{2}\right)^{\nu+2k}, \\ J_{-\nu}(x) &= \sum_{k=0}^{\infty}\frac{(-1)^{k}}{k!\Gamma(-\nu+k+1)} \left(\frac{x}{2}\right)^{-\nu+2k}.\end{aligned} \nonumber \]

    La solución general a la ecuación de orden de Bessel\(\nu\) es así

    \[y(x) = A J_{\nu}(x)+BJ_{-\nu}(x), \nonumber \]

    para cualquier valor no entero de\(\nu\). Esto también se mantiene para valores medio enteros (sin registros).
