The Alexander horned sphere is a pathological object in topology discovered by J. W. Alexander ( 1924 ). It is a particular topological embedding of a two-dimensional sphere in three-dimensional space. Together with its inside, it is a topological 3-ball , the Alexander horned ball , and so is simply connected ; i.e., ... | https://en.wikipedia.org/wiki/Alexander_horned_sphere |
In mathematics , the Alexander polynomial is a knot invariant which assigns a polynomial with integer coefficients to each knot type. James Waddell Alexander II discovered this, the first knot polynomial , in 1923. In 1969, John Conway showed a version of this polynomial, now called the Alexander–Conway polynomial , c... | https://en.wikipedia.org/wiki/Alexander_polynomial |

In general topology , an Alexandrov topology is a topology in which the intersection of an arbitrary family of open sets is open (while the definition of a topology only requires this for a finite family). Equivalently, an Alexandrov topology is one whose open sets are the upper sets for some preorder on the space.
