Properties of associated Legendre conical functions

Daniel A. Norman, Philip D. Mannheim, Tianye Liu

We present some new properties of associated Legendre conical functions of the first and second kind, $P_{- 1/2 + i τ}^{- 1/2 - K} (χ)$ and $Q_{- 1/2 + i τ}^{- 1/2 - K} (χ)$ . In particular we sh…

Exceptional points for associated Legendre functions of the second kind

Tianye Liu, Daniel A. Norman, Philip D. Mannheim

We consider the complex $ν$ plane structure of the associated Legendre function of the second kind $Q_{ν}^{- 1/2 - K} (cosh ρ)$ . We find that for any noninteger value for $K$ $Q^{-1/2-K}…
