Maass forms on GL(n) (awaiting review)

The term Maass form is used for automorphic forms on \( GL_{n} \) (for some positive integer n), which are not holomorphic. Instead of satisfying the Cauchy-Riemann equations (as holomorphic functions do), these functions are eigenfunctions of the Casimir element in the universal enveloping algebra of the Lie algebra of \( GL_{n} \).
