Intuitive Concepts in Elementary TopologyClassroom tested and much cited, this concise text offers a valuable and instructive introduction for undergraduates to the basic concepts of topology. It takes an intuitive rather than an axiomatic viewpoint, and can serve as a supplement as well as a primary text. A few selected topics allow students to acquire a feeling for the types of results and the methods of proof in mathematics, including mathematical induction. Subsequent problems deal with
Classroom-tested and much-cited, this concise text offers a valuable and instructive introduction for undergraduates to the basic concepts of topology. It takes an intuitive rather than an axiomatic viewpoint, and can serve as a supplement as well as a primary text.A few selected topics allow students to acquire a feeling for the types of results and the methods of proof in mathematics, including mathematical induction. Subsequent problems deal with networks and maps, provide practice in recognizing topological equivalence of figures, examine a proof of the Jordan curve theorem for the special case of a polygon, and introduce set theory. The concluding chapters examine transformations, connectedness, compactness, and completeness. The text is well illustrated with figures and diagrams.

Great product at a good price
Color: Black, Size: Medium
This sink caddy is made of sturdy material and helpful for holding the stuff on the edge of my sink. It's nice to be able to move the little drain spout to accommodate where I set it. It also allows me to move the divider to accommodate the size of what I put in there, so that's nice. It has an overall nice look. removing the tray to wash it out is very helpful. The only thing I don't care for is that sometimes when I grab the dish cloth, the little rod pops out. However, this is a minor inconvenience, and only when I'm in a hurry to grab the cloth. The price is very reasonable for the sturdy material.

Keeps my sink area neat and organized
Color: Black, Size: Medium
Really happy with this sink caddy! The 304 stainless steel feels sturdy and looks nice, and the auto drain spout keeps water from pooling on the counter. The divided sections easily hold my sponge, brush, and soap bottle without taking up much space.
I also like the removable towel bar and that there was no installation needed. Redy to use right out of the box. Simple, practical, and very useful for keeping the sink area tidy.
