Difference between Gδ set and Irrational number

Gδ set vs. Irrational number

In the mathematical field of topology, a Gδ set is a subset of a topological space that is a countable intersection of open sets. In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios (or fractions) of integers.

Similarities between Gδ set and Irrational number

Gδ set and Irrational number have 8 things in common (in Unionpedia): Complete metric space, Completely metrizable space, Countable set, Irrational number, Metric space, Rational number, Springer Science+Business Media, Topological space.

Complete metric space

In mathematical analysis, a metric space M is called complete (or a Cauchy space) if every Cauchy sequence of points in M has a limit that is also in M or, alternatively, if every Cauchy sequence in M converges in M. Intuitively, a space is complete if there are no "points missing" from it (inside or at the boundary).

Completely metrizable space

In mathematics, a completely metrizable space (metrically topologically complete space) is a topological space (X, T) for which there exists at least one metric d on X such that (X, d) is a complete metric space and d induces the topology T. The term topologically complete space is employed by some authors as a synonym for completely metrizable space, but sometimes also used for other classes of topological spaces, like completely uniformizable spaces or Čech-complete spaces.

Countable set

In mathematics, a countable set is a set with the same cardinality (number of elements) as some subset of the set of natural numbers.

Springer Science+Business Media

Springer Science+Business Media or Springer, part of Springer Nature since 2015, is a global publishing company that publishes books, e-books and peer-reviewed journals in science, humanities, technical and medical (STM) publishing.

Topological space

In topology and related branches of mathematics, a topological space may be defined as a set of points, along with a set of neighbourhoods for each point, satisfying a set of axioms relating points and neighbourhoods.

Gδ set and Irrational number Comparison

Gδ set has 40 relations, while Irrational number has 145. As they have in common 8, the Jaccard index is 4.32% = 8 / (40 + 145).
