contractibility

The muscle contractibility rose much more in the cell group.

The stronger condition, that the object have no holes of any dimension, is called contractibility.

See Contractibility of unit sphere in Hilbert space for more.

Increases in the sphincter thickness and muscle contractibility are thought to help improve symptoms.

Indeed, contractibility of a universal cover is the same, by Whitehead's theorem, as asphericality of it.

These results suggest an altered pseudopodial extension although a defect in contractibility could be involved as a secondary mechanism for formation of aberrant processes.

In 1932 Borsuk asked whether compactness together with contractibility could be a necessary and sufficient condition for the FPP to hold.

Note that we can drop "local contractibility" as part of the hypothesis, if we use Čech cohomology, which is designed to deal with local pathologies.

For instance, having a single point as a deformation retract would imply a space is path connected (in fact, it would imply contractibility of the space).

Contractibility can be easily seen by noting that the dunce hat embeds in the 3-ball and the 3-ball deformation retracts onto the dunce hat.

In other categories than topological spaces, the notion of contractibility has to be replaced by suitable analogs, such as acyclicity in the category of chain complexes.

Contractibility means that there is a homotopy F : Xx[0,1] X that continuously deforms X to a point.

Equivariant extensions have important applications in Teichmüller theory, for example they lead to a quick proof of the contractibility of the Teichmüller space of a Fuchsian group.

Dr. Wein said that in addition to surgery and biofeedback training, other treatments include electrical stimulation that exercises and strengthens both the bladder and sphincter, and drugs that increase sphincter resistance and decrease bladder contractibility.

Much earlier than the above referred paper, Russell noticed that the hypersurface has properties very similar to the affine 3-space like contractibility and was interested in distinguishing it from the affine 3-space as algebraic varieties, necessary for linearizing actions on .

FIBTEM eliminates the platelet contribution of clot formation by inhibiting the platelets irreversibly with cytochalasin D, a potent inhibitor of actin polymerization which disrupts actin microfilaments, an essential part of a cytoskeleton-mediated contractibility apparatus of the platelet.
