A geometric characterisation of real C*-algebras

Cho-Ho Chu

We characterise the positive cone of a real C*-algebra geometrically. Given an open cone $Ω$ in a real Banach space $V$ , with closure $Ω$ , we show that $Ω$ is the interio…

Peeling Property of Bondi-Sachs metrics for nonzero Cosmological Constant

Fangquan Xie, Xiao Zhang

In this paper, we show that the peeling property still holds for Bondi-Sachs metrics with nonzero cosmological constant under the boundary condition given by Sommerfeld's radiation…
