Armstrong Topology Comprehensive Overview
Prob 4.7: Describe each of the following spaces: (a) the cylinder with each of its boundary circles identified to a point; (b) the torus ... Prob 4.6: Give an example of an identification map which is neither open nor closed. Basic Basic
Prob 4.10: Let S^2 be the unit sphere in E^3 and define f: S^2 to E^4 by f(x,y,z) = (x^2 - y^2, xy, xz, yz). Show that f induces an ...
Summary & Highlights for Armstrong Topology
- Prob 4.5: Let X denote the union of the circles (x - (1/n))^2 + y^2 = (1/n)^2, n = 1, 2, 3,..., with the subspace

- Prob 4.9: Let f: X to X' be a continuous function and suppose we have partitions P, P' of X and X' respectively, such that if two ...
- Prob 4.8: Let X be a compact Hausdorff space. Show that the cone on X is homeomorphic to the one-point compactification of X x ...
