Title: Some Implications of Neighborhood Homogeneity

Abstract: A space X is called neighborhood homogeneous if for any points a and b of X, there exist neighborhoods U and V of and a homeomorphism f such that  f(U)=V and f(p)=q. First we will observe that in zero dimensional Hausdorff spaces, neighborhood homogeneity implies homogeneity. We then utilize that proof to generalize a construction from J. van Mill which decomposed R into disjoint homogeneous homeomorphic subsets. We will also provide an example of a space which is neighborhood homogeneous but not homogeneous as well illustrate the difficulties arise for applying neighborhood homogeneity to non-zero dimensional spaces.Refreshments are available at 3:00 PM in SC 313F.
