Abstract

One may consider the generalization of Jacobi polynomials and the Jacobi func- tion of the second kind to a general function where the index is allowed to be a complex number instead of a non-negative integer. These functions are referred to as Jacobi func- tions. In a similar fashion as associated Legendre functions, these break into two categories, functions which are analytically continued from the real line segment (−1, 1) and those con- tinued from the real ray (1, ∞). Using properties of Gauss hypergeometric functions, we derive multi-derivative and multi-integral representations for the Jacobi functions of the first and second kind.
