The second-order ordinary differential equation
(1) |
This differential equation has an irregular singularity at . It can be solved using the series method
(2) |
(3) |
Therefore,
(4) |
and
(5) |
for , 2, .... Since (4) is just a special case of (5),
(6) |
for , 1, ....
The linearly independent solutions are then
(7) |
|||
(8) |
These can be done in closed form as
(9) |
|||
(10) |
where is a confluent hypergeometric function of the first kind and is a Hermite polynomial. In particular, for , 2, 4, ..., the solutions can be written
(11) |
|||
(12) |
|||
(13) |
where is the erfi function.
If , then Hermite's differential equation becomes
(14) |
which is of the form and so has solution
