The reason I've given this long explanation (because I hope it will also help others studying Topology who have similarities), is because the path most Topology students follow is the following For a senior undergraduate or first year graduate-level course in Introduction to Topology. Appropriate for a one-semester course on both general and algebraic topology or separate courses treating each topic separately. Notes on the adjunction, compactification, and mapping space topologies from John Terilla's topology course. Below are links to answers and solutions for exercises in the Munkres (2000) Topology, Second Edition. The study of 1- and 2-manifolds is arguably complete – as an exercise, you can probably easily list all 1-manifolds without much prior knowledge, and inexplicably, much about manifolds of dimension greater than 4 is known. However, for a long time, many aspects of 3- and 4-manifolds had evaded study; thus developed the subfield of low-dimensional topology, the study of manifolds of dimension 4 or below. This is an active area of research, and in recent years has been found to be closely related to quantum field theory in physics.He was elected to the 2018 class of fellows of the American Mathematical Society.

Greatly expanded, full-semester coverage of algebraic topology—Extensive treatment of the fundamental group and covering spaces. What follows is a wealth of applications—to the topology of the plane (including the Jordan curve theorem), to the classification of compact surfaces, and to the classification of covering spaces. A final chapter provides an application to group theory itself.Topology, in broad terms, is the study of those qualities of an object that are invariant under certain deformations. Such deformations include stretching but not tearing or gluing; in laymen’s terms, one is allowed to play with a sheet of paper without poking holes in it or joining two separate parts together. (A popular joke is that for topologists, a doughnut and a coffee mug are the same thing, because one can be continuously transformed into the other.) If I want to broaden my knowledge of General Topology, what book do I go to next after Munkres? Should I learn some Pointfree Topology (Frame Theory)?. Also I should mention that I don't want to specialize in General Topology.

This book provides a convenient single text resource for bridging between general and algebraic topology courses. Two separate, distinct sections (one on general, point set topology, the other on algebraic topology) are each suitable for a one-semester course and are based around the same set of basic, core topics Each of the text's two parts is suitable for a one-semester course, giving instructors a convenient single text resource for bridging between the courses. The text can also be used where algebraic topology is studied only briefly at the end of a single-semester course. Ex.___ Advanced topics—Such as metrization and imbedding theorems, function spaces, and dimension theory are covered after connectedness and compactness. There are other subfields of topology. One subfield is algebraic topology, which uses algebraic tools to rigorously express intuitions such as “holes.” For example, how is a hollow sphere different from a hollow torus? One may say that the torus has a “hole” in it while the sphere does not. This intuition is captured by the notion of the fundamental group, which, (very) loosely speaking, is an algebraic object that counts the number of “holes” of a topological space. There are other useful algebraic tools, including various homology and cohomology theories. These can all be viewed as a mapping from the category of topological spaces to algebraic objects, and are very good examples of functors in the language of category theory; it is for this reason that many algebraic topologists are also interested in category theory.Access-restricted-item true Addeddate 2022-01-25 17:07:37 Autocrop_version 0.0.5_books-20210916-0.1 Bookplateleaf 0008 Boxid IA40327619 Camera Sony Alpha-A6300 (Control) Collection_set printdisabled External-identifier

While I certainly have a lot more Differential Topology and Algebraic Topology to learn (and I look forward to it), I also feel like I should learn a bit more of General Topology. This seminar is an introduction to knot theory, and there is often one each year. Like other junior seminars, students are expected to learn and present a topic on their own. Topics covered vary, but typically include tri-colorability of knots and links, numerical knot invariants such as the crossing number, unknotting number and bridge number, and polynomial invariants such as the Jones polynomial and the Alexander-Conway polynomial. More advanced students may learn about homology invariants, such as the Khovanov homology and the Heegaard Floer homology. NEW - Greatly expanded, full-semester coverage of algebraic topology—Extensive treatment of the fundamental group and covering spaces. What follows is a wealth of applications—to the topology of the plane (including the Jordan curve theorem), to the classification of compact surfaces, and to the classification of covering spaces. A final chapter provides an application to group theory itself. Deepen students' understanding of concepts and theorems just presented rather than simply test comprehension. The supplementary exercises can be used by students as a foundation for an independent research project or paper. Ex.___ After making my way through Dover's excellent Algebraic Topology and Combinatorial Topology (sadly out of print), I was recommended this on account of its 'clean, accessible' (1) layout, and its wise choice of 'not completely dedicating itself to the Jordan (curve) theorem'. (2)Among Munkres' contributions to mathematics is the development of what is sometimes called the Munkres assignment algorithm. A significant contribution in topology is his obstruction theory for the smoothing of homeomorphisms. [3] [4] These developments establish a connection between the John Milnor groups of differentiable structures on spheres and the smoothing methods of classical analysis. I found it to be an even better approach to the subject than the Dover books. That said, they're all highly recommended. However, one new(er) to the concepts of algebraic and general topology will probably find this book to be more accessible, even if the algebraic treatment is too light to properly slake the gullet of a more seasoned topologist. Carefully guides students through transitions to more advanced topics being careful not to overwhelm them. Motivates students to continue into more challenging areas.
