I am wondering if someone knows good references. I am looking for expansions of Hermite functions, which gives connections between rates of decay and smoothness of coefficients.
Thank you for your suggestions.

I've found Special Functions: An Intro. to the Classical Functions of Mathematical Physics by Nico Temme very helpful.
