Cardinality of natural numbers
WebApr 11, 2024 · Sometimes, the cardinality of a field is not known a priori. For example, a proxy that transforms a data stream from a row-oriented format into a series of columnar-encoded batches (e.g., OpenTelemetry collector) may not be able to predict in advance whether a field will have a fixed number of distinct values.

WebThe cardinality of the set of points on a one-metre line segment and on a two-metre line is the same, but they have different measure (length, in this case). Similarly, the Hilbert space-filling curve fills all the points, but being a curve, it has measure 0 relative to the square it fills (it has length, but no area). WebAs for the cardinalities, you are right; A × B = 6, A × D = D = N = ℵ 0 ("countable infinity") More generally spoken, there are subsets of A × B looking like A or B, namely sets of the form A × { b }, { a } × B with a ∈ A, b ∈ B, but A, B are no subsets of A × B.

WebSince the natural numbers have cardinality each real number has digits in its expansion. Since each real number can be broken into an integer part and a decimal fraction, we get: where we used the fact that On the other hand, if we map to and consider that decimal fractions containing only 3 or 7 are only a part of the real numbers, then we get http://www.cwladis.com/math100/Lecture5Sets.htm
