61Merkle-Hellman — (MH) was one of the earliest public key cryptosystems and was invented by Ralph Merkle and Martin Hellman in 1978. [Ralph Merkle and Martin Hellman, Hiding Information and Signatures in Trapdoor Knapsacks, IEEE Trans. Information Theory , 24(5),… …
62Extended Euclidean algorithm — The extended Euclidean algorithm is an extension to the Euclidean algorithm for finding the greatest common divisor (GCD) of integers a and b : it also finds the integers x and y in Bézout s identity: ax + by = gcd(a, b). ,(Typically either x or… …
63Unit (ring theory) — In mathematics, a unit in a (unital) ring R is an invertible element of R , i.e. an element u such that there is a v in R with : uv = vu = 1 R , where 1 R is the multiplicative identity element.That is, u is an invertible element of the… …
64Virasoro algebra — In mathematics, the Virasoro algebra (named after the physicist Miguel Angel Virasoro) is a complex Lie algebra, given as a central extension of the complex polynomial vector fields on the circle, and is widely used in string theory.DefinitionThe …

66Multiplicative group of integers modulo n — In modular arithmetic the set of congruence classes relatively prime to the modulus n form a group under multiplication called the multiplicative group of integers modulo n. It is also called the group of primitive residue classes modulo n. In… …
67Binary moment diagram — A binary moment diagram (BMD) is a generalization of the binary decision diagram (BDD) to linear functions over domains such as booleans (like BDDs), but also to integers or to real numbers.They can deal with boolean functions with complexity… …
68Contributions of Leonhard Euler to mathematics — The 18th century Swiss mathematician Leonhard Euler (1707–1783) is among the most prolific and successful mathematicians in the history of the field. His seminal work had a profound impact in numerous areas of mathematics and he is widely… …
69Henselian ring — In mathematics, a Henselian ring (or Hensel ring) is a local ring in which Hensel s lemma holds. They were defined by harvtxt|Azumaya|1951, who named them after Kurt Hensel. Some standard references for Hensel rings are… …
70Central series — In mathematics, especially in the fields of group theory and Lie theory, a central series is a kind of normal series of subgroups or Lie subalgebras, expressing the idea that the commutator is nearly trivial. For groups, this is an explicit… …
