  2. John L. Kelley - Wikipedia

    en.wikipedia.org/wiki/John_L._Kelley

    Kelley's 1955 text, General Topology, which eventually appeared in three editions and several translations, is a classic and widely cited graduate-level introduction to topology. An appendix sets out a new approach to axiomatic set theory, now called Morse–Kelley set theory, that builds on Von Neumann–Bernays–Gödel set theory.

  3. List of topologies - Wikipedia

    en.wikipedia.org/wiki/List_of_topologies

    The following is a list of named topologies or topological spaces, many of which are counterexamples in topology and related branches of mathematics. This is not a list of properties that a topology or topological space might possess; for that, see List of general topology topics and Topological property .

  4. Topology - Wikipedia

    en.wikipedia.org/wiki/Topology

    A three-dimensional model of a figure-eight knot.The figure-eight knot is a prime knot and has an Alexander–Briggs notation of 4 1.. Topology (from the Greek words τόπος, 'place, location', and λόγος, 'study') is the branch of mathematics concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling ...

    George Finlay Simmons (March 3, 1925 [1] – August 6, 2019) [2] [3] was an American mathematician who worked in topology and classical analysis. He is known as the author of widely used textbooks on university mathematics.

  6. General topology - Wikipedia

    en.wikipedia.org/wiki/General_topology

    General topology grew out of a number of areas, most importantly the following: the detailed study of subsets of the real line (once known as the topology of point sets; this usage is now obsolete) the introduction of the manifold concept; the study of metric spaces, especially normed linear spaces, in the early days of functional analysis.

  8. Open and closed maps - Wikipedia

    en.wikipedia.org/wiki/Open_and_closed_maps

    In mathematics, more specifically in topology, an open map is a function between two topological spaces that maps open sets to open sets. [1] [2] [3] That is, a function : is open if for any open set in , the image is open in . Likewise, a closed map is a function that maps closed sets to closed sets.

  9. Pointed space - Wikipedia

    en.wikipedia.org/wiki/Pointed_space

    In mathematics, a pointed space or based space is a topological space with a distinguished point, the basepoint.The distinguished point is just simply one particular point, picked out from the space, and given a name, such as , that remains unchanged during subsequent discussion, and is kept track of during all operations.
