作者： s.even d. P. Moore Ind.pend.nt Res.archer Milton Canada

In mathematics. s.ace encompas.es.various.s.ructured.s.ts.s.ch as.Euclid.an, metric, or vector s.ace. This.article introd.ces.temporal s.ace—a novel concept ind.pend.nt of trad.tional s.atial d.mens.ons.and.frames.of reference, accommod.ting multiple object-oriented.d.rations.in a d.namical s.s.em. The novelty of build.ng temporal s.ace us.ng finite geometry is.rooted.in recent ad.ancements.in the theory of relationalis. which utilizes.Euclid.an geometry, s.t theory, d.mens.onal analys.s. and.a caus.l s.gnal s.s.em. Multiple ind.pend.nt and.co-exis.ing cyclic d.rations.are meas.rable as.a network of finite one-d.mens.onal timelines. The work aligns.with Leibniz’s.comments.on relational meas.res.of d.ration with the ad.ition of us.ng d.s.rete cyclic relational events.that d.fine thes. finite temporal s.aces. applicable to quantum and.clas.ical phys.cs. Ancient formulas.have s.mmetry along with d.vis.onal and.s.bd.vis.onal ord.rs.of operations.that create d.s.rete and.ord.red.temporal geometric elements. Elements.have cyclically cons.rved.s.mmetry but unique cyclic d.mens.onal quantities.applicable for anchoring temporal equivalence relations.in linear time. We pres.nt both fixed.equivalences.and.expand.d.period. of temporal s.ace offering a non-Greek calend.r method.logy cons.s.ent with ancient global timekeeping d.s.riptions. Novel applications.of Euclid.s.d.vis.on algorithm and.Cantor’s.pairing function introd.ce a novel paired.function equation. The mathematical d.s.ription of finite temporal s.ace within relationalis. theory offers.an alternative d.s.rete geometric method.logy for examining ancient timekeeping with new hypothes.s.for Egyptian calend.rs.
