SUMMARY

The discussion confirms that there is no Rodrigues-type formula applicable to Bessel functions due to their infinite Taylor series representations. Instead, Bessel functions can be expressed using generating functions, which relate them to derivatives of elementary functions. For detailed insights, refer to section 2.1 of the provided document from Penn State University.

Is there any relation between Rodrique formula and Bessel's equation? Is it necessary to apply Rodrigue formula in the Bessel's Equation?
 
Physics news on Phys.org
I do not believe that there is a Rodrigues-type formula for the Bessel functions, since there is no representation of a Bessel function in terms of a polynomial of finite order. The Taylor series representations are infinite series. There is a slightly different type of presentation called a generating function that can be used to express the Bessel functions in terms of derivatives of an elementary function. See sect. 2.1 of http://www.math.psu.edu/papikian/Kreh.pdf for some details.
