General topology | Separation axioms | Properties of topological spaces
In mathematics, a sober space is a topological space X such that every (nonempty) irreducible closed subset of X is the closure of exactly one point of X: that is, every irreducible closed subset has a unique generic point. (Wikipedia).

Ask the Space Lab Expert: What is Space?
Have you ever wanted to go to Space? In this first episode of Space Lab, Brad and Liam from "World of the Orange" take you on an adventure to discover exactly what is Space. You'll find out about the solar system, the big bang, Sci-Fi movies that are becoming reality, and more!

Kolchin: Irreducibility = Has Deformations for Sober Topological Spaces
This is the key lemma we want to apply to prove irreducibility theorems. This is based of what is done in a paper of Ishii and Kollar and is the basis of something I have done with with Lance and James.

Where Is The Coldest Place In The Universe?
The Boomerang Nebula is the coldest place in the universe, colder even than deep space at -459°F. But why this regions of space is colder than space itself has remained a mystery to astronomers until very recently. ------------------------------------------------------ #Space #Universe #
