Exempel på hur man kan använda COUNTABLE i en mening

• The meaning of "negligible" depends on the mathematical context; for instance, it can mean finite, countable, or null.
• In mathematics, a set is countable if either it is finite or it can be made in one to one correspondence with the set of natural numbers.
• This can be characterized as a set that can be covered by a countable union of intervals of arbitrarily small total length.
• In 1901, when Max Planck was developing the distribution function of statistical mechanics to solve the ultraviolet catastrophe problem, he realized that the properties of blackbody radiation can be explained by the assumption that the amount of energy must be in countable fundamental units, i.
• In particular, every continuous function on a separable space whose image is a subset of a Hausdorff space is determined by its values on the countable dense subset.
• In mathematical analysis and in probability theory, a σ-algebra ("sigma algebra"; also σ-field, where the σ comes from the German "Summe") on a set X is a nonempty collection Σ of subsets of X closed under complement, countable unions, and countable intersections.
• Though only a few classes of transcendental numbers are known, partly because it can be extremely difficult to show that a given number is transcendental, transcendental numbers are not rare: indeed, almost all real and complex numbers are transcendental, since the algebraic numbers form a countable set, while the set of real numbers and the set of complex numbers are both uncountable sets, and therefore larger than any countable set.
• A space is a Baire space if the intersection of any countable collection of dense open sets is dense; see Baire space.
• An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique class of objects, where the "object" or class may be an idea, person, physical countable object (or class thereof), or physical noncountable substance (or class thereof).
• In mathematics, a Borel set is any set in a topological space that can be formed from open sets (or, equivalently, from closed sets) through the operations of countable union, countable intersection, and relative complement.
• In general though, the PMF is used in the context of discrete random variables (random variables that take values on a countable set), while the PDF is used in the context of continuous random variables.
• In mathematics, a probability measure is a real-valued function defined on a set of events in a σ-algebra that satisfies measure properties such as countable additivity.
• Two is most commonly a determiner used with plural countable nouns, as in two days or I'll take these two.
• The word "chad" has been used both as a mass noun (as in "a pile of chad") and as a countable noun (pluralizing as in "many chads").
• Burton also discusses proofs for different types of infinity, including countable and uncountable sets.
• If the graph is countable, the vertices are well-ordered and one can canonically choose the smallest suitable vertex.
• Pips are small but easily countable items, such as the dots on dominoes and dice, or the symbols on a playing card that denote its suit and value.
• This allows an axiomatic construction of numbers and ordinal arithmetic, namely, the integers, reals, the countable infinity, and entire towers of infinite ordinals.
• Rubin, use the term transfinite cardinal to refer to the cardinality of a Dedekind-infinite set in contexts where this may not be equivalent to "infinite cardinal"; that is, in contexts where the axiom of countable choice is not assumed or is not known to hold.
• The definition that follows is based on the notions of meagre (or first category) set (namely, a set that is a countable union of sets whose closure has empty interior) and nonmeagre (or second category) set (namely, a set that is not meagre).
