Abstract

Let MM be a smooth, compact manifold and let Nμ\mathcal{N}_{\mu} denote the set of Riemannian metrics on MM with smooth volume density μ\mu. For a given g0Nμg_0\in \mathcal{N}_{\mu}, we show that if dim(M)5\dim(M)\ge 5, then there exists an open and dense subset Yg0Tg0Nμ\mathcal{Y}_{g_0} \subset T_{g_0} \mathcal{N}_{\mu} (in the CC^{\infty} topology) so that for each hYg0h\in \mathcal{Y}_{g_0}, the (Nμ,L2)(\mathcal{N}_{\mu},L^2) Ebin geodesic γh(t)\gamma_h(t) with γh(0)=g0\gamma_h(0)=g_0 and γh(0)=h\gamma_h'(0)=h satisfies limt\lim_{t \to \infty} R(γh(t))=R(\gamma_h(t))=-\infty, uniformly.
