WebThat example is not a regular space. Examples of Tychonoff G δ spaces that are not normal are the Sorgenfrey plane and the Niemytzki plane. In a first countable T 1 space, every singleton is a G δ set. That is not enough for the space to be a G δ space, as shown for example by the lexicographic order topology on the unit square. http://stoimenov.net/stoimeno/homepage/teach/homework07-11nov19.pdf WebFrom my perspective as an analyst, non-metrizable spaces usually arise for one of the following reasons: Separation axiom failure: the space is not, e.g., normal. This mostly happens when the space is not even Hausdorff (spaces that are Hausdorff but not normal are usually too exotic to arise much). how many milliliters in 3.4 liters

WebA topological space X is called orderable or linearly orderable [1] if there exists a total order on its elements such that the order topology induced by that order and the given topology on X coincide. The order topology makes X into a completely normal Hausdorff space . The standard topologies on R, Q, Z, and N are the order topologies. Webc (R) on R, are not metrizable so as to be complete. Nevertheless, some are expressible as colimits (sometimes called inductive limits) of Banach or Fr echet spaces, and such descriptions su ce for many applications.

The order topology makes S into a completely normal Hausdorff space. Since the lexicographical order on S can be proven to be complete, this topology makes S into a compact space. At the same time, S contains an uncountable number of pairwise disjoint open intervals, each homeomorphic to the real line, for example the intervals for . So S is not separable, since any dense subset has to contain at least one point in each . Hence S is not metrizable (since any compact me…

WebNov 23, 2014 · So immediately we can see that the long line cannot be metrizable since it is sequentially compact but not compact. So it would be impossible to create a “distance” function, which made sense, on the long line which lead to the construction of all the open sets we have.
