ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 57: Manifolds and cell complexes Introduction Manifolds are spaces like the sphere which look locally like Euclidean space. In particular, these are the spaces in which we can discuss (locally-)linear maps, and the spaces in which to discuss smoothness. They include familiar surfaces. Cell complexes are spaces made of pieces which are part of Euclidean space, generalizing polyhedra. These types of spaces admit very precise answers to questions about existence of maps and embeddings; they are particularly amenable to calculations in algebraic topology; they allow a careful distinction of various notions of equivalence. These are the most classic spaces on which groups of transformations act. This is also the setting for knot theory. History See the article on Topology at St Andrews. Perhaps it is easiest to use classic literature to understand differential topology: Flatland ; here are two Backup sites and the home page for Project Gutenberg Applications and related fields There are two other topology pages: Algebraic topology definitions and computations of fundamental groups, homotopy groups, homology and cohomology.

The first book contains the basic core material along with a number of optional topics of a relatively elementary nature. The other two books, which are largely independent of each other, are provisionally titled "Vector Bundles and K-Theory" and "Spectral Sequences in Algebraic Topology." These are only partially written see below.

Rowland Manifold This entry contributed by Todd Rowland A manifold is a topological space which is locally Euclidean (i.e., around every point, there is a neighborhood which is topologically the same as the open unit ball in ). To illustrate this idea, consider the ancient belief that the Earth was flat as contrasted with the modern evidence that it is round. This discrepancy arises essentially from the fact that on the small scales that we see, the Earth does indeed look flat (although the Greeks did notice that the last part of a ship to disappear over the horizon was the mast). In general, any object which is nearly "flat" on small scales is a manifold, and so manifolds constitute a generalization of objects we could live on in which we would encounter the round/flat Earth problem, as first codified by More formally, any object that can be "charted" is a manifold.

Cyclic branched covering along knots or links in S are examples of such manifolds. First we will recall basic facts in 3-dimensional topology and then introduce the main tools needed for the proof. We will use results from the lectures of Leeb and Otal. Bernhard Leeb (Universität Tübingen) The geometry of cone manifolds and the Orbifold Theorem Summary: Cone manifolds are singular metric spaces with curvature bounded below and with sigularities of a very restricted type. They play a central role in the geometrization of orbifolds. We will discuss basic geometric results concerning their small-scale structure and possible degenerations, and explain how they are used in the proof of the Orbifolds Theorem.

SECTIONS: Steam Basics Types Of Steam Traps Inverted Bucket ... Talk To Us Not Determined Manifolds: Multiple Components for Maximum Effect If one superior product is good, combining several superior products is bound to be better, right? Right. Combining is exactly the idea behind the Armstrong manifolds. By combining Armstrong steam traps, valves and manifolds, you can handle steam distribution, steam main drainage, tracer line valving and steam trap applications more effectively and economically. A centerpiece of many of Armstrong' manifolds is the piston valve, chosen for duty here because of its superior service record in steam installations around the world. Leakage to atmosphere is extremely rare, even without any maintenance. The piston valve also features dual sealing, thanks to two graphite and stainless steel valve sealing rings. Flexible disc springs automatically provide leak tightness by exerting pressure that keeps the upper and lower valve sealing rings compressed at all times.

Trott Isospectral Manifolds Roughly speaking, isospectral manifolds are Drums that sound the same, i.e., have the same eigenfrequency spectrum. Two drums with differing area perimeter , or genus can always be distinguished. However, Kac (1966) asked if it was possible to construct differently shaped drums which have the same eigenfrequency spectrum. This question was answered in the affirmative by Gordon et al. (1992). Two such isospectral manifolds (which are 7- polyaboloes ) are shown in the left figure above (Cipra 1992). The right figure above shows another pair obtained from the original ones by making a simple geometric substitution. Another example of isospectral manifolds is the pair of polyabolo configurations known as bilby (left figure) and hawk (right figure). The figures above show scaled displacements for a number of eigenmodes of these manifolds (M. Trott, pers. comm., Oct. 8, 2003).

M anifolds are where all smaller piping is connected into a larger header, or manifold. A supply manifold is where all the piping used to supply, or deliver, the hot water to the radiant panel is connected to a common pipe. A manifold has several other items conveniently built into it. For example, it is desirable to know the temperature of the hot water being supplied to the radiant system, therefore, a temperature gage is installed. An air vent for purging air from the system is installed as is a hose bib for initial filling and draining of the system. Sometimes isolation valves are installed for isolating a portion of the system, or shutting off the flow of water to enable maintenance to take place, for example. A supply manifold is also where the control of hot water flow to the radiant system is done. We use ball valves for this. These can be manual or automatically opened and closed with a zone valve actuator. An actuator just opens or closes the ball valve. Fancier actuators can even modulate the ball valve or continuously open or close the ball valve in response to the heating needs of the space being served. The difference is a 'regular' actuator is an on/off device, in other words, the valve is either all the way open, or all the way closed. A modulating actuator can open or close the valve to any position required, depending on the heat required in the space being served.
