Going into space is dangerous. A fair number of astronauts and cosmonauts have died during space missions and others have face with life-threatening situations. Astronauts go into space knowing that even a seemingly minor malfunction could prove fatal.
The key to math is Metric!!
How is the metric system use in America? How is the metric system use in Australia? How is the metric system use in Japan? How is the metric system use in Thailand? How is the metric system use in sweden? How is the metric system use in anywhere? Know the answer now?
Prove that if it were true then there must be a contradiction.
A topological space is simply a set, B, with topology t (see the related link for a definition), and is often denoted as B, t which is similar to how a metric space is often denoted; B, D.
prove that every metric space is hausdorff and first countable
In mathematics, a zero-dimensional topological space is a topological space that ... any point in the space is contained in exactly one open set of this refinement.
A topological domain is a connected and open subset of a topological space. Key characteristics include being connected, open, and having a well-defined boundary. These characteristics impact the overall structure of the space by determining how the domain interacts with the rest of the space and how it can be manipulated or transformed within the space.
The question doesn't make sense, or alternatively it is true by definition. A Hilbert Space is a complete inner product space - complete in the metric induced by the norm defined by the inner product over the space. In other words an inner product space is a vector space with an inner product defined on it. An inner product then defines a norm on the space, and every norm on a space induces a metric. A Hilbert Space is thus also a complete metric space, simply where the metric is induced by the inner product.
Cl is often used as shorthand for closure, e.g. if B, tis a topological space then Cl B is the closure of B. The closure of a topological space B, t is defined as the intersection of all of the closed sets containing B. The closure of C ⊂ B where B, D is a metric space is defined as all of the elements of B that have a 0 metric with C, written asCl C = {b Є B | D(b, C) = 0}.See related links.

A Betti number is a number associated to each topological space and dimension, giving an approximate number of holes of that dimension in that space.
A compact metric space is not necessarily complete. Compactness only guarantees that every sequence in the space has a convergent subsequence, while completeness requires that every Cauchy sequence converges to a point in the space.
no
A metric on a set is complete if every Cauchy sequence in the corresponding metric space they form converges to a point of the set in question. The metric space itself is called a complete metric space. See related links for more information.
