 Manifold - Wikipedia, the free encyclopedia
A finite cylinder is a manifold with boundary.
Manifolds are important mathematics and physics because they allow more complicated structures to be expressed and understood in terms of the relatively well-understood properties of simpler spaces.
Manifolds need not be connected (all in "one piece"); thus a pair of separate circles is also a manifold.

 The center manifold theorem
The formal Taylor series of the center manifold is usually not convergent, but in many cases the Taylor series for the bifurcating solutions do converge (assuming of course, that the nonlinear terms f and g have convergent Taylor expansions).
A proof of the center manifold theorem is well beyond the scope of this course.
If the center manifold is not unique, this means, of course, that they must lie on every center manifold.

 Manifold Theory: (W)holes and Boundaries
Perhaps not coincidentally, it is precisely these manifolds that arise in the new physics of conformal field theory, superstring theory and quantum gravity.
In quantum gravity, we may expect that a similar representation will hold, except that the two-dimensional manifold with boundary will be replaced by a multidimensional one.
Unfortunately, multidimensionality goes against the grain of conventional linear mathematical thought, and despite a recent broadening of attitudes (notably associated with the study of multidimensional nonlinear phenomena in chaos theory), the theory of multidimensional manifolds with boundary remains somewhat underdeveloped.

 Edelbrock Air Gap Performer Intake Manifold
Substituting the 914-cfm carb for the 1020-cfm carb on the race manifold reduced the flow loss due to the presence of the carb to 0.82 percent of that shown by the bare manifold.
Again, because the manifold is now allowing the head to communicate greater demands to the carb, installing the carb causes a proportionately greater drop in airflow.
Achieving this meant each manifold must be paired with the optimal carb for that intake manifold, leaving only the manifold as a variable.

 Installing an Intake Manifold Insulator/Spacer
While this does not entirely determine the IAT or even the temperature of the manifold, it is a large factor- it tells you how much insulation or resistance the manifold has from the heating effects of the head itself.
Since the surface area where the head contacts the manifold (the flange) is the largest area for heat exchange, this is an important bit of information.
I also checked the temperature of the manifold (near where I checked on the head) and found it to be no more than 5 degrees cooler than the head.
