By William Fulton

This ebook introduces the real principles of algebraic topology by means of emphasizing the relation of those principles with different parts of arithmetic. instead of deciding on one viewpoint of contemporary topology (homotropy concept, axiomatic homology, or differential topology, say) the writer concentrates on concrete difficulties in areas with a number of dimensions, introducing in basic terms as a lot algebraic equipment as useful for the issues encountered. This makes it attainable to determine a greater diversity of vital gains within the topic than is usual in introductory texts; it's also in concord with the ancient improvement of the topic. The ebook is aimed toward scholars who don't unavoidably intend on focusing on algebraic topology.

Attribute sessions are important to the trendy learn of the topology and geometry of manifolds. They have been first brought in topology, the place, for example, they can be used to outline obstructions to the lifestyles of sure fiber bundles. attribute sessions have been later outlined (via the Chern-Weil thought) utilizing connections on vector bundles, therefore revealing their geometric aspect.

This publication develops rigorous foundations for parametrized homotopy idea, that is the algebraic topology of areas and spectra which are regularly parametrized by means of the issues of a base house. It additionally starts off the systematic research of parametrized homology and cohomology theories. The parametrized global offers the normal domestic for plenty of classical notions and effects, resembling orientation idea, the Thom isomorphism, Atiyah and Poincaré duality, move maps, the Adams and Wirthmüller isomorphisms, and the Serre and Eilenberg-Moore spectral sequences.

The purpose of this ebook is to build different types of areas which include all of the C? -manifolds, but additionally infinitesimal areas and arbitrary functionality areas. To this finish, the innovations of Grothendieck toposes (and the common sense inherent to them) are defined at a leisurely speed and utilized. by means of discussing issues corresponding to integration, cohomology and vector bundles within the new context, the adequacy of those new areas for research and geometry may be illustrated and the relationship to the classical method of C?

As a particular case it yields one form of the so-called de Rham theorem, which states ˇ that the de Rham cohomology of a differentiable manifold and the Cech cohomology of the constant sheaf R are isomorphic. 11. Let F be a sheaf of abelian groups on X. A resolution of F is a collection of sheaves of abelian groups {Lk }k∈N with morphisms i : F → L0 , dk : Lk → Lk+1 such that the sequence d i d 0 → F → L0 →0 L1 →1 . . is exact. If the sheaves L• are acyclic (fine) the resolution is said to be acyclic (fine).

6) G2 i2 `BB BB BB k2 BB / G2 | | || || j2 | ~| E2 is exact. 5). 6) can be iterated, and we get a sequence of exact triangles Gr ir `BB BB BB kr BB / Gr | | || || jr | ~| Er where each group Er is the cohomology group of the differential module (Er−1 , dr−1 ), with dr−1 = jr−1 ◦ kr−1 . As we have already noticed, due to the assumption that the filtration K• has finite length , the groups Gr stabilize when r ≥ + 1, and the morphisms ir : Gr → Gr 2. THE SPECTRAL SEQUENCE OF A FILTERED COMPLEX 57 become injective.

One has a diagram of inclusions ? U @@ @@ jU ~~ ~ @@ ~ ~ @@ ~~ U A@ @ X ~> ~ ~~ ~~ ~~ jV @@ @@ @ V V Defining i(σ) = ( U ◦ σ, − V ◦ σ) and p(σ1 , σ2 ) = jU ◦ σ1 + jV ◦ σ2 , the exactness of the Mayer-Vietoris sequence is easily proved. The morphisms i and p commute with the homology operator ∂, so that one obtains a long homology exact sequence involving the homologies H• (A), H• (V ) ⊕ H• (V ) and H•U (X). 9. Prove that for any ring R the homology of the sphere S n with coefficients in R, n ≥ 2, is Hk (S n , R) = R for k = 0 and k = n 0 for 0 < k < n and k > n .
