... fα fβ−1 : fβ (Uα ∩ Uβ ) → fα (uα ∩ Uβ ) is a conformal map of each component. Via the maps {fα } and the transition property, angles in C are carried up to well defined angles on R. 2. Denote by F = π1 (R) its fundamental group. As an abstract group, F is independent of basepoint; the fundamental gr ...

... There should be p-adic homotopy theories for every prime p analogous to Sullivan’s Real homotopy theory. A norm on Q induces a unique topology on any finite dimensional vector V space over Q; hence V determines Vp a finite dimensional topological vector space over Qp. If V is infinite dimensional, t ...

... When discussing the concept of connectedness, we often come across the equivalent criterion that a space is connected if and only if any continuous map from it to the discrete space {0,1} is constant. It would be interesting to see what concept arises if the discrete space of two points is replaced ...

... then α ∗ β is homotopic to γ ∗ δ. 3. Suppose that a topological space X has a function m : X × X → X. Show that if α and β are any paths in X, the definition (α · β)(t) = m(α(t), β(t)) is homotopy invariant, in the sense that [α] ∗ [β] = [α ∗ β] is well-defined on homotopy classes of paths. 4. Show ...

... (b) Let G be any finitely presented group. Show that there is a 4-manifold that has G as its fundamental group (Hint: Let F be the free group on the generators, R the set of relations. Start with X, the 4-manifold from part a). Represent each relation in R by a loop in X. Go ahead and assume that th ...

(b) The space G is a topological group meaning that G is a group and also a Hausdorff topological space such that the multiplication and map taking each element to its inverse are continuous operations. Given two loops based at the identity e in G, say α(s) and β(s), we have two ways to combine them ...
