I’ve been spending a lot of time rereading a number of older papers on stable causality. Basically I want to get a handle on the types of techniques needed to manipulate them. For this Seifert’s 1977 paper is a gem. My particular interest is on the extension of a time function from a compact neighbourhood …

Stable causality implied by causality + ?
I’ve been reading some interesting papers showing that stable causality holds on a spacetime assuming that causality + some other condition holds. This is some really interesting stuff. Causality conditions on spacetimes describe how nicely behaved physics is. Causality is the condition that there are no closed causal curves. That is, no travelling back in …
