On bτ-closed sets
... 2. bτ -closed sets and their relationships In [10] the relationships between various types of generalized closed sets have been summarized in a diagram. We shall expand this diagram by adding b-closed sets and bτ -closed sets. Proposition 2.1. Every ss-closed set in a topological space (X, τ ) is b- ...

Normed vector space
... Of special interest are complete normed spaces called Banach spaces. Every normed vector space V sits as a dense subspace inside a Banach space; this Banach space is essentially uniquely defined by V and is called the completion of V. All norms on a finite-dimensional vector space are equivalent fro ...

... 3. If X is a space which is homeomorphic to a subspace A of a space Y , then X is said to be embedded in Y . Give an example of spaces A and B for which A can be embedded in B and B can be embedded in A, but A and B are not homeomorphic. (Simple examples can be found in R.) Let A = (0, 1) and let B ...

Generalized Normal Bundles for Locally
... Again, let M denote an n-manifold and To C M' denote those paths w such that w(t) = w(O), 0 < t < 1, if, and only if, t = 0. Thus, To are those paths which never return to their initial position (see Nash [10]). Furthermore, let T denote To plus all the constant paths in M. Define a map by p(w) = w( ...
