are called *Generalized Associated Legendre Functions*. As in the case of
(14.21.1), the solutions are hypergeometric functions, and
(14.29.1) reduces to (14.21.1) when
${\mu}_{1}={\mu}_{2}=\mu $. For properties see Virchenko and Fedotova (2001) and
Braaksma and Meulenbeld (1967).

For inhomogeneous versions of the associated Legendre equation, and properties of their solutions, see Babister (1967, pp. 252–264).
