In mathematics, a topological space X has the fixed point property if all continuous mappings from X to X have a fixed point.Educational > Mathematics > Ideas/Explanations/Wiki or Mathworld lookupsnarkyTue, 01 May 2007 02:50:22 GMTFixed Point Theorem Finite-Closed - Topology Q+A Board

Does a space which has the finite closed topology have the fixed-point property? I really don't know how to go about this, but my initial thoughts are: - This should be related to continuous functions and connectedness.Educational > Mathematics > Ideas/Explanations/Wiki or Mathworld lookupsnarkyTue, 01 May 2007 02:24:24 GMTFixed-point theorem - Wikipedia
http://en.wikipedia.org/wiki/Fixed-point_theorem
In mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F(x) = x), under some conditions on F that can be stated in general terms. Results of this kind are amongst the most generally useful in mathematics. The Banach fixed point theorem gives a general criterion guaranteeing that, if it is satisfied, the procedure of iterating a function yields a fixed point. By contrast, the Brouwer fixed point theorem is a non-constructive result: it says that any continuous function from the closed unit ball in n-dimensional Euclidean space to itself must have a fixed point, but it doesn't describe how to find the fixed point (See also Sperner's lemma).Educational > Mathematics > Ideas/Explanations/Wiki or Mathworld lookupsnarkyTue, 01 May 2007 02:51:32 GMT
