  1. List of all non-homeomorphic $T_0$ topologies on a finite set

    The list of topologies are to be given as a comma-separated list of such hexadecimal numbers in a preformatted block, with at most 8 topologies in a single row. These conventions make the topologies …

  2. On the definition of weak and weak-* topologies

    Jun 10, 2022 · I have been studying topological vector spaces, and despite going over numerous resources, the definitions of weak and weak-* topologies have been causing me some confusion. I …

  3. real analysis - Equivalent Topologies - Mathematics Stack Exchange

    Nov 4, 2011 · In the case of topologies coming from norms on a vector space, two topologies are equivalent according to your definition if they are the same. For general topologies I find this …

  4. How to list all possible topologies - Mathematics Stack Exchange

    Sep 7, 2019 · That are 3 more topologies (all homeomorphic to each other, if you already know that notion). One extra set that is a doubleton, so $\ {a,b\}$, $\ {a,c\}$ or $\ {b,c\}$, again three extra …

  5. general topology - Show that the Topologies of $\mathbb {R}_l$ and ...

    14 Here, $\mathbb {R}_l$ is the lower limit topology on $\mathbb {R}$ and $\mathbb {R}_K$ is the K-topology on $\mathbb {R}$. I understand the proof that these topologies are strictly finer than …

  6. Examples of topologies on R - Mathematics Stack Exchange

    Apr 14, 2017 · There are a gazillion topologies on any infinite set and very few of these will be metrizable. Interesting non-metric topologies specific to $\Bbb {R}$, are the Sorgenfrey topology and …

  7. Applications of Hausdorff distance and 'hyper'-topologies

    Oct 23, 2020 · Can anyone please give some examples of intersting Applications\uses of Hausdorff distance and such 'hyper'-topologies? Even with relation to simplifying other known mathametical …

  8. Newest 'general-topology' Questions - Mathematics Stack Exchange

    Everything involving general topological spaces: generation and description of topologies; open and closed sets, neighborhoods; interior, closure; connectedness ...

  9. general topology - How to show two topologies are the same ...

    May 2, 2021 · I am new to topology, and have been given an assignment to show that two topologies, on the same set, are the same (respectively). So far, in my class, we have only discussed metric …

  10. how to find the unique smallest topology? [duplicate]

    If you show just one of: (i) there is a smallest topology containing all the T (ii) there is a largest topology contained in all the T, then the other statement can be seen as a corollary. It's a little easier to verify …
