Let( X, d) be a metric space associated with the metric d.
The rational numbers with the same distance also form a metric space, but are not complete.
A metric space is compact if and only if it is complete and totally bounded.
Therefore the Cantor set itself is a metric space, by using that same metric. .
A metric space is now considered a special case of a general topological space. .
The rational numbers with the same distance function also form a metric space, but not a complete one.
In the case X is a metric space, the Borel algebra in the first sense may be described generatively as follows.
By using this formula as distance,Euclidean space becomes a metric space….
Let X{\displaystyle\scriptstyle X} be a metric space with distance function d{\displaystyle\scriptstyle d}.
A metric space is a tuple(M, d) where M is a set and d is a metric on M, that is, a function.
Using the absolute value to measure distances,the irrational numbers become a metric space which is not complete.
We often omit d and just write X for a metric space if it is clear from the context what metric we are using.
A metric space is a tuple(M, d) where M is a set and d is a metric on M, that is, a function d: M×M→ℝ such that.
Often d is omitted and one just writes M for a metric space if it is clear from the context what metric is used.
This generalises the Euclidean space example,since Euclidean space with the Euclidean distance is a metric space.
The Cantor set is a subset of the reals,which are a metric space with respect to the ordinary distance metric; .
To prove this fact,note that any open set in a metric space is the union of an increasing sequence of closed sets.
However, they can also be defined and studied in any space of mathematical objects that is equipped with a definition of"nearness"(a topological space) or"distance"(a metric space).
Given a injective function f from any set A to a metric space(X, d), d(f(x), f(y)) defines a metric on A.
The concept can be defined naturally in a metric space where a notion of distance between elements of the space is defined, but it can be generalized to topological spaces where we have no concrete way to measure distances.
Edit distance with non-negative cost satisfies the axioms of a metric giving rise to a metric space of strings, when the following conditions are met.
The Cantor set is a subset of the reals,which are a metric space with respect to the ordinary distance metric; therefore the Cantor set itself is a metric space, by using that same metric. .
The topological definition of open sets generalizes the metric space definition: If one begins with a metric space and defines open sets as before, then the family of all open sets is a topology on the metric space.
When the two curves are embedded in a metric space other than Euclidean space, such as a polyhedral terrain or some Euclidean space with obstacles, the distance between two points on the curves is most naturally defined as the length of the shortest path between them.
If M isany connected Riemannian manifold, then we can turn M into a metric space by defining the distance of two points as the infimum of the lengths of the paths(continuously differentiable curves) connecting them.
Let X be a Polish space, that is, a topological space such that there is a metric d on X which defines the topology of X and which makes X a complete separable metric space.
