theory of counting
1Counting problem (computability theory) — In computability theory, a counting problem is a type of computational problem. If R is a search problem then :c R(x)=vert{ymid R(x,y)}vert ,is the corresponding counting function and:#R={(x,y)mid yleq c R(x)}denotes the corresponding counting… …
2Counting problem (complexity) — In computational complexity theory and computability theory, a counting problem is a type of computational problem. If R is a search problem then is the corresponding counting function and denotes the corresponding counting problem. Note that cR… …
3Counting — is the action of finding the number of elements of a finite set of objects. The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or… …
4Counting points on elliptic curves — An important aspect in the study of elliptic curves is devising effective ways of counting points on the curve. There have been several approaches to do so, and the algorithms devised have proved to be useful tools in the study of various fields… …
5Counting sort — In computer science, counting sort is an algorithm for sorting a collection of objects according to keys that are small integers; that is, it is an integer sorting algorithm. It operates by counting the number of objects that have each distinct… …
6Counting (music) — In music, counting is a system of regularly occurring sounds that serve to assist with the performance or audition of music by allowing the easy identification of the beat. Commonly, this involves verbally counting the beats in each measure as… …
7Counting measure — In mathematics, the counting measure is an intuitive way to put a measure on any set: the size of a subset is taken to be the number of elements in the subset, if the subset is finite, and ∞ if the subset is infinite.[1] Formally, start with a… …
8Double counting (accounting) — Double counting in accounting is an error whereby a transaction is counted more than once, for whatever reason. But in social accounting it also refers to a conceptual problem in social accounting practice, when the attempt is made to estimate… …
9Prime-counting function — In mathematics, the prime counting function is the function counting the number of prime numbers less than or equal to some real number x cite book |first=Eric |last=Bach |coauthors=Shallit, Jeffrey |year=1996 |title=Algorithmic Number Theory… …
10Chiral perturbation theory — (ChPT) is an effective field theory constructed with a Lagrangian consistent with the (approximate) chiral symmetry of quantum chromodynamics (QCD), as well as the other symmetries of parity and charge conjugation. ChPT is a theory which allows… …
