Topology is the mathematical research of the main easy geometrical constitution of an area. Mathematical physics makes use of topological areas because the formal skill for describing actual area and time. This booklet proposes a very new mathematical constitution for describing geometrical notions comparable to continuity, connectedness, obstacles of units, and so forth, so one can supply a greater mathematical software for figuring out space-time. this can be the preliminary quantity in a two-volume set, the 1st of which develops the mathematical constitution and the second one of which applies it to classical and Relativistic physics.
The booklet starts with a quick historic assessment of the advance of arithmetic because it pertains to geometry, and an outline of normal topology. the recent concept, the speculation of Linear buildings, is gifted and in comparison to typical topology. the idea of Linear constructions replaces the foundational inspiration of normal topology, the open set, with the concept of a continuing line. Axioms for the idea of Linear constructions are laid down, and definitions of different geometrical notions constructed in these phrases. a variety of novel geometrical homes, akin to an area being intrinsically directed, are outlined utilizing those assets. purposes of the speculation to discrete areas (where the traditional conception of open units will get little buy) are fairly famous. the math is constructed up via homotopy idea and compactness, in addition to how one can symbolize either affine (straight line) and metrical structure.
