an initial element) and it is not dicontractible. On the other hand, the category X
itself is dicontractible but not s-contractible. The strongest notion of homotopy is
the concept of sd-homotopy. Definition 3.7. Let /, g : C — > V be functors. A strictly

C.q.f.d. Corollaire : Un métrique Zest un A.R. si et seulement si c'est un A.N.R.
contractible. Preuve : Nous avons déjà vu qu'un A.R. est un A.N.R. contractible.
Pour démontrer la réciproque, on ne restreint pas la généralité en supposant que

Economics of contracting
More specifically, consider the following polar cases: (i) At one extreme, a world
with fully contractible actions: contracts can then fully determine the entire
interaction between the parties; this case encompasses the implementation
literature a ...

Evidemment un espace euclidien est partout localement contractible. Plus
généralement, soit R un sous-ensemble d'un espace euclidien; soit a e R, ô > 0;
supposons que si x est un point de R distant de a de moins de ô, le segment ax
fasse ...

We will define it using an embedding in a regular space, although the
corresponding definitions could be made independently. Let us fix a regular
closed embedding g : X — > X of the complex space X in the complex manifold X,
a contractible ...

A closed subset X of a space M is said to be W - contractible in M provided the
identity map i: X-+X is W-homotopic rel. M to a constant map. Eeplacing in this
definition the letter W by the letter 8, one gets the notion of the 8 - contractible
subsets ...

A d-space X is future contractible, or past contractible, or contractible in n steps, if
it has such a deformation retract, at a point. X is future contractible if and only if
there is a homotopy idX -* v with a constant map v: X — X; then x+ ...

Assume that A rs B 3 C and C is contractible to a set C, c B in B: B~(B — C)uC,, Ct
< C. Then, under our assumptions, A=(A— B) uB ~{A-B)\j{B-C)\jC1, ={A-C) uC, ,
and C is contractible to C^ 'mA: (11) if C ct Cl in Band Be A, then C ct Cy in A. As ...

Proposition 4,3, (fm,gm) is an isomorphism between their homology groups. □

Sur la dimension de Gabriel des modules
Next I'll show that X create equalizers of x-
contractible pairs. Let f,g: (A,x») — *"(B,
Xn) be a pair of X-
contractible Comod-C morphisms and m: K — ▻- A be an
equalizer of f,g: <A,X(xA)> ▻ <B,X(xB)> in C*-Mod. Then there exist C*-module ...
