Title: Signature character formulas and unitary representations 2 (https://researchseminars.org/talk/atlas/9/)
by Jeffrey Adams (University of Maryland) as part of Real reductive groups/atlas

Abstract
More details about how atlas computes signatures: realize a representation as a Langlands quotient J(delta\otimes nu), then deform nu to zero. At nu=0, the form is unitary. As nu changes, the signature of the form changes only at the (finitely many) values of t*nu (t in [0,1]) for which I(delta\otimes t*nu) is reducible.
