An Introduction to Algebraic Topology
D A hemisphere is contractible but not convex, so that the converse of Theorem
1.7 is not true. After proving Theorem 1.6, we observed that Lemma 0.2 implies
that S" is not contractible. Exercises 1.1. Let x0,x,e* and let /J: X -* X for i = 0, ...

Lectures on Coarse Geometry
By way of variety, we give in this section a calculation of the coarse cohomology
for a uniformly contractible space, defined below. Depinition 5.24. Let X be a
proper coarse space. One says that X is uniformly contractible if for every
controlled ...

Topological Fixed Point Theory of Multivalued Mappings
A space X is said to be locally contractible at a point x0 ∈ X provided for each ε >
0, there exists δ > 0 (δ < ε) and a homotopy h:[0,1] × B(x0 ,δ) → B(x0 ,ε) such that:
h(x,0) = x0 and h(x,1) = x, for every x ∈ B(x0 ,δ); in other words the ball B(x0 ,δ) ...

Introduction to General Topology
1.12 A space X is called contractible if the identity map Ix : X-> X is null-
homotopic. Prove that: (i) A contractible space is path connected. (ii) Every map
into or from a contractible space is null-homotopic (iii) A space is contractible iff it
is ...
If M is a metric space and has a metric in which M is starlike, then M is
contractible. Proof: Let p be the point and d the metric on M such that from each
point x in M there is a unique arc px congruent to an interval. Define a mapping h:
M X I1 ...

Lusternik-Schnirelmann Category
It is clear that Ji can be covered by two contractible open subsets: each subset is
equal to the union of a fattened hemisphere with two semi-circles containing the
basepoint. It also is obvious that Ji ~ J^ (see Exercise 3.5) and that Ji can be ...

Cellular Structures in Topology
Since X is contractible, it has the homotopy type of a CW-complex. Suppose there
is a CW-structure for X. The points (0,0) and (0, 1/n), for all neN\{0}, cannot be
interior points of open cells of dimension > 0, in view of the theorem of invariance

The Infinite-dimensional Topology of Function Spaces
Y] denotes We say that [A', 1'] is trivial if it contains one point only (i.e., all
continuous functions from A' to 1' are homotopic and hence nullhomotopic). As
we will see, homotopic functions have much in common. A space X is called
contractible ...

Discrete Geometry for Computer Imagery: 13th International ...
In the case of assertion 6, if Xj = x, for some j =/= I, then the case M. = {1, . . . , k} \ {j
} of (*) implies that PU\J^=1 Xi is contractible, and so the hypotheses of assertion
6 are inconsistent with assertion 5. In other words, if assertion 5 is true then ...
