Ince equation explained

In mathematics, the Ince equation, named for Edward Lindsay Ince, is the differential equation

w\prime\prime+\xi\sin(2z)w\prime+(η-p\xi\cos(2z))w=0.

When p is a non-negative integer, it has polynomial solutions called Ince polynomials. In particular, when

p=1,η\pm\xi=1

, then it has a closed-form solution[1]

w(z)=Ce-iz(e2iz\mp1)

where

C

is a constant.
