“…Theorem 3 considers the local stability for a finite interval around t = 0. Theorem 4 extends Bernstein's Theorem to include local stability, and extends the scalar theory in [33] to vectors. We emphasize that both theorems have a common covariance matrix Q which is not the case in [33] but is important to generalize Theorem 1 and to develop further results for product channels and for broadcast channels.…”

“…The discussion in [30] describes several other stability metrics, including the Lévy metric [31]. We instead follow [32], [33] (see also [34]) and consider a metric in the characteristic function (c.f.) domain.…”

“…The paper [33] develops the following stability theorem. Let P ϵ be the class of (X 1 , X 2 ) for which X 1 and X 2 are independent and X 1 + X 2 and X 1 − X 2 are ϵ-dependent in the c.f.…”

Stability properties of Bernstein's characterization of Gaussian vectors are derived. Stability leads to a soft doubling argument through which one can prove capacity theorems without requiring the existence of capacity-achieving distributions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
