About this deal

It is perhaps not perfectly edited, but seems to essential reading as a source for modern unstable homotopy theory. This emphasis also illustrates the book's general slant towards geometric, rather than algebraic, aspects of the subject. I'll close this box and throw it open to the floor by sharing what may be the first such textbook available as a massive set of online notes. This is a reminder for me to go back and try simplifying the proof given the insight gained from the original. The only thing that comes to mind that might be controversial is the usage of Delta complexes, which I’ve heard is seldom used elsewhere and doesn’t do much to simplify material.

A unique feature is the inclusion of many optional topics not usually part of a first course due to time constraints: Bockstein and transfer homomorphisms, direct and inverse limits, H-spaces and Hopf algebras, the Brown representability theorem, the James reduced product, the Dold-Thom theorem, and Steenrod squares and powers.

But I wanted to know if anyone might have any advice for someone that wants to learn most efficiently/effectively when reading this book. The viewpoint is quite classical in spirit, and stays well within the confines of pure algebraic topology.The readership of the n-Lab is not restricted to Algebraic Topologists of course, but the above list of notes would be useful to have readily available. I'm hoping that will not only expose me to the cutting edge,but allow me to work with one of the greats. Many simplicial complexes arising in practice have an associated metric space structure on the vertex set but not on the complex, e.

A couple of notes from courses by Mike Hopkins on elliptic cohomology and related stuff: 1995, 1999.Now it is true that he doesn't assume too much background in abstract algebra (knowing the basics of groups, rings, and modules is more than sufficient). This book deals with a hard subject, but every effort has been made to explain and motivate the ideas involved before they are dealt with rigorously. This book was written to be a readable introduction to algebraic topology with rather broad coverage of the subject. Yes, I would rate its difficulty a notch above your typical introductory text in, say, analysis, algebra or point-set topology.

Although I think Hatcher's book is littered with great, well-thought out examples, I personally didn't like it.Otherwise, while you may be able to fool yourself into thinking you know what the hell is going on, you won't really have anything but a superficial grasp of the basics. I feel that I should add my own answer here, now that I am more or less done reading homotopy and homology from Hatcher's text. Covers classical topics related to the vector field problem, the EHP sequence, and Adams's work on Im(J). By bidding on, or purchasing this item, you are agreeing to us sharing your name and address details with that 3rd party supplier to allow us to fulfil our contractual obligations to you. This introductory text is suitable for use in a course on the subject or for self-study, featuring broad coverage and a readable exposition, with many examples and exercises.

He doesn't walk you through every tedious step, so at the beginning you will have to read more slowly until your mind gets smarter about filling in the blanks--which it will learn to do if you put in the time. One of the most commonly used tools in TDA is persistent homology (PH), which can extract topological properties from data at various scales.All posts and comments should be directly related to mathematics, including topics related to the practice, profession and community of mathematics. After Peter May and Kate Ponto released their new book, there are very readable introductions to many of the topics on the "second level" of algebraic topology.
