Abstract: Abstract We study the quasi-stationary behavior of the birth–death process with an entrance boundary at infinity. We give by the h-transform an alternative and simpler proof for the exponential convergence of conditioned distributions to a… read more here.

Abstract: We prove positive mass theorems for asymptotically hyperbolic and asymptotically locally hyperbolic Riemannian manifolds with black-hole-type boundaries. An interesting global invariant of asymptotically hyperbolic general relativistic initial data sets is the energy-momentum vector m ≡… read more here.
