Abstract
There are two kinds of recurrence relations for the spherical functions P m l . The first are those with the same m but different l. The second are those with the same l but different m. The spheroidal functions are extensions of the spherical functions. Recurrence relations of the first kind are obtained for the spheroidal functions in recent studies. Using the shape invariance method in supersymmetric quantum mechanics, we investigate the second type of recurrence relations for the spheroidal functions. The results show that the second kind of recurrence relation can not be extended to the spheroidal functions.
