... spaces in which no separation axioms are assumed unless explicitly stated. Let A be a subset of a space X. For a subset A of (X, τ ), Cl(A) and Int(A) denote the closure of A with respect to τ and the interior of A with respect to τ , respectively. Recently, as generalization of closed sets, the not ...

... In fact, it turns out that every closed subscheme of an affine scheme is of this form. It is interesting to look at some examples. Example 12.17. Let X = A2k . First consider a = hy 2 i. The support of Y is the x-axis. However the scheme Y is not reduced, even though it is irreducible. It is clear f ...

METRIC SPACES AND UNIFORM STRUCTURES
... METRIC SPACES AND UNIFORM STRUCTURES The general notion of topology does not allow to compare neighborhoods of different points. Such a comparison is quite natural in various geometric contexts. The general setting for such a comparison is that of a uniform structure. The most common and natural way ...

ROLLING OF COXETER POLYHEDRA ALONG MIRRORS 1
... Also “mirrors” are hyperplanes of reflections. They divide the space Mn into chambers. The group G acts on the set of chambers simply transitively. We denote the reflection with respect to a mirror Y by sY . Each facet is contained in a unique mirror. 1.3. General Coxeter groups. Take a symmetric p ...

3-manifold
In mathematics, a 3-manifold is a space that locally looks like Euclidean 3-dimensional space. Intuitively, a 3-manifold can be thought of as a possible shape of the universe. Just like a sphere looks like a plane to a small enough observer, all 3-manifolds look like our universe does to a small enough observer. This is made more precise in the definition below.
