Corpus analysis for Pseudometric
- In this selection, "pseudometric" usually appears in the middle of the sentence. The average example has 20.4 words, and this corpus slice is mostly made up of statements.
- Around the word, single, complete, space and definition stand out and add context to how "pseudometric" is used.
- Recognizable usage signals include a complete pseudometric space is and a single pseudometric. That gives this page its own corpus information beyond isolated example sentences.
- By corpus frequency, "pseudometric" sits close to words such as aargau, abacos and abboud, which helps place it inside the broader word index.
Example types with pseudometric
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
The function d is a pseudometric on M. Every metric is a pseudometric. (13 words)
Other examples include: * Every metric space is Tychonoff; every pseudometric space is completely regular. (14 words)
That is, points in a pseudometric space may be "infinitely close" without being identical. (14 words)
Less trivially, it can be shown that a uniform structure that admits a countable fundamental system of entourages (and hence in particular a uniformity defined by a countable family of pseudometrics) can be defined by a single pseudometric. (38 words)
Note that the symmetric difference of two distinct sets can have measure zero; hence the pseudometric as defined above need not to be a true metric. (26 words)
Indeed, as discussed above, such a uniformity can be defined by a single pseudometric, which is necessarily a metric if the space is Hausdorff. (24 words)
Example sentences (8)
Indeed, since a metric is a fortiori a pseudometric, the pseudometric definition furnishes M with a uniform structure.
The function d is a pseudometric on M. Every metric is a pseudometric.
Indeed, as discussed above, such a uniformity can be defined by a single pseudometric, which is necessarily a metric if the space is Hausdorff.
Less trivially, it can be shown that a uniform structure that admits a countable fundamental system of entourages (and hence in particular a uniformity defined by a countable family of pseudometrics) can be defined by a single pseudometric.
Note that the symmetric difference of two distinct sets can have measure zero; hence the pseudometric as defined above need not to be a true metric.
Other examples include: * Every metric space is Tychonoff; every pseudometric space is completely regular.
Proof The following is a standard proof that a complete pseudometric space is a Baire space.
That is, points in a pseudometric space may be "infinitely close" without being identical.
