symmetry properties of sasakian space forms
... space of constant curvature one. Theorem 2.2.([15]) A Sasakian manifold is semi-symmetric if and only if it is a space of constant curvature one. Theorem 2.3. Every Sasakian space forms M 2n+1 (c) is pseudo-symmetric, more precisely for every Sasakian space forms: R · R = Q(g, R). Proof. As is well ...

The computer screen: a rectangle with a finite number of points
... An important problem in such work is the replacement of regions by their boundaries; this can result in considerable data compression. In the Euclidean plane, the Jordan curve theorem is the key tool. Recall that a Jordan curve is a homeomorphic (= continuous one-one, inverse continuous) image of th ...

... for the reals this definition is equivalent to the above definition. • Example : For every set X the discrete topology is simply given by 2X and generated by {{x} | x ∈ X}. (X, 2X ) is compact iff X is finite as {{x} | x ∈ X} is an open cover. • Example : For every set X the trivial topology is give ...

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.
