SUMMARY

The differential equation discussed is given by $$f(z) + 2zf'(z) + f''(z) = 0$$ and is identified as a Sturm-Liouville differential equation. The general solution is expressed as $$f(z) = e^{-z^2} \big( c_1 + c_2 \Phi(\sqrt{3}z) \big)$$, where $\Phi(x)$ denotes the probit function. The discussion clarifies that this equation does not belong to the Hermite family of equations.

$$
f(z) + 2zf'(z) + f''(z) = 0 ~.
$$
I ran into it somewhere and it does not look to be Hermite. I think it has the general solution
$$
f(z) = e^{-z^2} \big( c_1 + c_2 \Phi(\sqrt{3}z) \big)
\quad \textnormal{($\Phi(x)$ is probit function.)}
$$
You might have to correct me on the solution, but is there a name to it?

This can be transformed into
##\dfrac{d}{dz} \left ( e^{z^2} \dfrac{df}{dz} \right ) + e^{z^2} f(z) = 0##

This is a Sturm-Louville differential equation.
