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

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 ...
