In mathematics , an arithmetic group arithmetic subgroup in a linear algebraic group G defined over a number field K is a subgroup of G K that is commensurability mathematics commensurable with G O , where O is the ring of integers of K . Here two subgroups A and B of a group are commensurable when their Intersection set theory intersection has finite Index of a subgroup index in each of them. It can be shown that this condition depends only on G , not on a given matrix representation of G . Examples of arithmetic groups include therefore the groups GL sub n sub Z . The idea of arithmetic group is closely related to that of lattice discrete subgroup lattice in a Lie group . Lattices in that sense tend to be arithmetic, except in well defined circumstances. The exact relationship of the two concepts was established by the work of Grigory Margulis Margulis on superrigidity . The general theory of arithmetic groups was developed by Armand Borel and Harish Chandra the description of their fundamental domain s was in classical terms the reduction theory of algebraic form s.

Unary coding , sometimes called thermometer code , is an entropy encoding that represents a natural number , n , with n ones followed by a zero if natural number is understood as non negative integer or with n &minus 1 ones followed by a zero if natural number is understood as strictly positive integer .

In digital communications , differential coding is a technique used to provide unambiguous signal reception when using some types of modulation . It makes data to be transmitted to depend not only on the current bit or symbol , but also on the previous one. The common types of modulation that require differential coding include phase shift keying and quadrature amplitude modulation . Purposes of differential coding To demodulate BPSK one needs to make a local oscillator synchronous with the remote one. This is accomplished by a carrier recovery circuit. However, a carrier can be recovered in different ways, depending upon a valid phases count 2 for BPSK . For this coding, if a carrier is recovered incorrectly, the received data are inverted. Assuming that math x i math is a bit intended for transmission, and math y i math is a bit actually transmitted differentially encoded , if math y i y i 1 oplus x i, qquad 1 math is transmitted, then on the decoding side math x i y i oplus y i 1 . qquad ... arithmetic modulo 2 addition.

Saturation arithmetic is a version of arithmetic in which all operations such as addition and multiplication are limited to a fixed range between a minimum and maximum value. If the result of an operation is greater than the maximum, it is set clamped to the maximum if it is below the minimum, it is clamped to the minimum. The name comes from how the value becomes saturated once it reaches the extreme values further additions to a maximum or subtractions from a minimum will not change the result. For example, if the valid range of values is from 100 to 100, the following operations produce the following ... fail in saturation arithmetic.

In mathematics , an arithmetic progression AP or arithmetic sequence is a sequence of number s such that the difference between the consecutive terms is constant. For instance, the sequence 3, 5, 7, 9, 11, 13, is an arithmetic progression with common difference of 2. If the initial term of an arithmetic progression is math a 1 math and the common difference of successive members is d , then the n th term of the sequence is given by math a n a 1 n 1 d, math and in general math a n a m n m d. math A finite portion of an arithmetic progression is called a finite arithmetic progression and sometimes just called an arithmetic progression.

In mathematical logic , Heyting arithmetic sometimes abbreviated HA is an axiomatization of arithmetic in accordance with the philosophy of intuitionism . It is named after Arend Heyting , who first proposed it. Heyting arithmetic adopts the axioms of Peano arithmetic PA , but uses intuitionistic logic as its rules of inference. In particular, the law of the excluded middle does not hold in general, though the induction axiom can be used to prove many specific cases. For instance, one can prove that nowrap 1 &forall x , y &isin N x y &or x &ne y is a theorem any two natural number s are either equal to each other, or not equal to each other . In fact, since is the only Predicate mathematics predicate symbol in Heyting arithmetic, it then follows that, for any quantifier free formula p , nowrap 1 &forall x , y , z , &hellip &isin N p &or ¬ p is a theorem where x , y , z &hellip are the free variables in p . Kurt G del studied the relationship between Heyting arithmetic and Peano arithmetic. He used the G del Gentzen negative translation to prove in 1933 that if HA is consistent, then PA is also consistent. Heyting arithmetic should not be confused with Heyting algebra s, which are the intuitionistic analogue of Boolean algebra structure Boolean algebras .
