In the algebraic approach, one finds a correspondence between spaces and groups that respects the relation of homeomorphism or more general homotopy of spaces.

Maunder Snippet view — Fundamental groups and homology and cohomology groups are not only invariants of the underlying topological space, in the sense that two topological spaces which are homeomorphic have the same associated groups, but their associated morphisms also correspond — a continuous mapping of spaces induces a group homomorphism on the associated groups, and these homomorphisms can be used to show non-existence or, much more deeply, existence of mappings.

The presentation of the homotopy theory and the account of duality in homology manifolds make the text ideal for a course on either homotopy or homology theory. The translation process is usually carried out by means of the homology or homotopy groups of a topological space.

Homotopy Groups and CWComplexes. My library Help Advanced Book Search. Algebraic topology — Wikipedia This class of spaces is broader and has some better categorical properties than simplicial complexesbut still retains a combinatorial nature that allows for computation often with a much smaller complex.

Homotopy and Simplicial Complexes. Although algebraic topology primarily uses algebra to study topological algebbraic, using topology to solve algebraic problems is sometimes also possible. Intuitively, homotopy groups record information about the basic shape, or holes, of a topological space. Maunder Courier Corporation- Mathematics — pages 2 Reviews https: In homology theory and algebraic topology, cohomology is a general term for a sequence of abelian groups defined from a co-chain complex.

Examples include the planethe sphereand the toruswhich can all be realized in three dimensions, but also the Klein bottle and real projective plane which cannot be realized in three dimensions, but can be realized in four dimensions. Maunder has provided many examples and exercises as an aid, and the notes and references at the end of each chapter trace the historical development of the subject and also point the way to more advanced results.

Two major ways in which this can be done are through fundamental groupsor more generally homotopy theoryand through homology and cohomology groups.

Algebraic topology — C. Maunder — Google Books In general, all constructions of algebraic topology are functorial ; the notions of categoryfunctor and natural transformation originated here. This was extended in the s, when Samuel Eilenberg and Norman Steenrod generalized this approach. The author has given much attention to detail, yet ensures that the reader knows where he is going.

Algebraic topology, for example, allows for a convenient proof that any subgroup of a free group is again a free group. Views Read Edit View history. Whitehead to meet the needs of homotopy theory. Homology and cohomology groups, on the other hand, are abelian and in many important cases finitely generated. TOP Related Posts.

## Algebraic Topology

In Stock Overview Based on lectures to advanced undergraduate and first-year graduate students, this is a thorough, sophisticated and modern treatment of elementary algebraic topology, essentially from a homotopy theoretic viewpoint. The presentation of the homotopy theory and the account of duality in homology manifolds make the text ideal for a course on either homotopy or homology theory. The idea of algebraic topology is to translate problems in topology into problems in algebra with the hope that they have a better chance of solution. The translation process is usually carried out by means of the homology or homotopy groups of a topological space. Much of the book is therefore concerned with the construction of these algebraic invariants, and with applications to topological problems, such as the classification of surfaces and duality theorems for manifolds.
