Mathematik für Physiker 2: Basiswissen für das Grundstudium der Experimentalphysik

Die für Studienanfanger geschriebene „Mathematik für Physiker'' wird in Zukunftvom Springer-Verlag betreut. Erhalten bleibt dabei die Verbindung einesakademischen Lehrbuches mit einer detaillierten Studienunterstützung. DieseKombination hat bereits vielen Studienanfangern geholfen, sich die Inhalte desLehrbuches selbständig zu erarbeiten.

Example text

Clearly IF (S 0 ) is a single point. Let B be a cell complex such that S n = |B|, and let β be an n-cell of B. Any element x ∈ IF (S n ) can be represented by a block bundle ξ over B. Let k, l be trivialisations of ξ|β, ξ|B − β, and let h = k−1 l : F × ∂β−−→F × ∂β. Since F is compact, there are finite simplicial complexes K, L with |K| = F × β, |L| = F × (B − β) and such that h is simplicial. Clearly the simplicial isomorphism class of the triple (K, L, h) determines x completely. But there are only countably many such classes (of triples), so IF (S n ) is countable.

Then θ induces isomorphisms θ∗ : πr (GF /P LF ) −−→ πr ((G/P L)F ) for r ≥ 1. Proof. Since the proof is essentially the same as the proof of Theorem 5, we shall not give the details. To prove that θ∗ is surjective, let B, β, ξ, Q, W be as above. Since Q has a boundary ∂Q such that π1 (∂Q)−−→π1 (Q − W ) is an isomorphism, it is unnecessary to cut out a disc from Q. 3 of [17] to construct a manifold E ⊃ W with boundary ∂E and a simple homotopy equivalence ψ : E, ∂E−−→Q, ∂Q with ψ|W equal to the identity.

Similarly i : E(∂ξ|C)−−→p−1 |C| ∩ ∂E is a homotopy equivalence, so i is a homotopy equivalence of pairs. 1 of [5] that (p−1 |C|, p−1 |C| ∩ ∂E, p|p−1 |C|, ib(ξ)) represents S(j ∗ x), so j ∗ S(x) = S(j ∗ x). This completes the proof of Lemma 7. Recall that wI ∈ IF (B P LF ), wH ∈ HF (BGF ) are the universal elements. There is a based map χ : B P LF −−→BGF such that S(wI ) = χ∗ (wH ). This defines the based homotopy class of χ uniquely. Consider the topological space L = {(x, ψ)} of pairs with x ∈ B P LF , ψ : I−−→BGF such that χ(x) = ψ(0), ψ(1) = bpt, with (bpt,constant) as base-point.
