DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Thank you guys, the causal sets brings me to recent research that may be linked to my personal research and framework starting from a... -
DavidMartin posted the thread Graduate When can transitivity emerge from cycle-suppressing dynamics? in Set Theory, Logic, Probability, Statistics.Let V be a finite set and let R⊆V×V be a directed binary relation. Assume that R is not assumed to be transitive or acyclic a priori...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Back to origin : Suppose we have a directed weighted relation and define a stability condition that suppresses cycles. Under what...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Type two hyphens (--) it generaly convert to em dash. I use that format in Visual Studio editor and .md files.

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.I don’t mean metaphysically fundamental — I mean structurally weaker. Szekeres’ signal relation is already assumed to satisfy certain...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.I’m not asking whether partial orders can model spacetime (as in causal sets), but whether they can emerge from non-order relations ?

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Could we come back to the sens of my question and ignore the emerging remaining ? :smile: Let me restate the core question more...

@OmniThoughts Please don't post chatbot output here. If any of us wanted to have a conversation with a chatbot then we would just ask... -
DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.That’s a fair request and didn's saw it sorry. By a law, I mean a dynamical rule governing evolution — for example Newton’s second law...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Let me sharpen the question slightly. Suppose one starts with a directed relational structure R(a,b) that is not assumed to be...

Hi David, Sadly Zenodo is not a peer-reviewed reputable journal. I encourage you to read our global guidelines (url is in my signature...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Suppose one starts not from a partial order, but from a non-symmetric compatibility relation R(a,b)≠R(b,a), with no metric assumed...

DavidMartin replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.So the question becomes: is there any intermediate structure — weaker than a full Lorentzian metric — that is sufficient to induce a...
