The Sorgenfrey lineGiv32375 Givenchy Cocktail Dress White Black and 7x4qZO (after Robert Sorgenfrey?, a mathematical descendant of R.L. Moore?) is the real line , but topologized by taking as topological basis the collection of half-open intervals [Elegant Women Short Dress Daily Sleeve Blue a,Daily Short Elegant Dress Blue Women Sleeve b). This is sometimes called the lower limit topology?, and the Sorgenfrey line is often denoted by l.

The Sorgenfrey line and spaces derived from it, notably the Sorgenfrey plane l×l (with the product topology), is a rich source for counterexamples in general topology. For example, the Sorgenfrey line is a (T1) Black fit neck slim jumper V FPq1nF and even a paracompact space, but the Sorgenfrey plane fails to be normal (and thus is not paracompact either). The Sorgenfrey plane is also an example of a separable space, but admitting an uncountable discrete subspace (which is thus not separable), showing that separability is not a hereditary property.
