This video illustrates operations on open sets (symbolized by burning objects). The fire symbolizes that open sets have no border. The union of two open sets is again open. The intersection of to open sets is also open. Let X be any set. Every collection T of subsets of X that contains the empty set and X itself and satisfies the two above properties (finite intersections und arbitrary unions stay in T) is called a topoloy on X. A space X with a topology T is called a topological space.This Video was produces for a topology seminar at the Leibniz Universitaet Hannover. http://www-ifm.math.uni-hannov...

Por fin alguien explica la genesis de los huesos de melocotón!

Sure! I clarified the explanation as you suggest.

That's an excellent allegory for open sets -- thanks.I believe your remarks need to be changed to finite intersections and arbitrary unions of open sets are open sets.For example, please consider the countable intersection of (-1/n, 1/n) for n = 1, 2, 3, ...Its intersection is { 0 }, which is a closed set.
For those considering buying a new vehicle, don't forget to check out the new 2008 Toyota FJ Cruiser. Great for adventures off road, just for cruising around town, or running to the store.

The new 2008 Toyota FJ Cruiser seats five and comes in two-tone with a Voodoo Blue, Titanium Metallic, Black Diamond, Sun Fusion, Sandstorm or Brick body color and White top. The interior fabric color is Dark Charcoal, while the dash, center instrument panel trim and the door inserts match the body.
