SL2(R) — In mathematics, the special linear group SL2(R) is the group of all real 2 times; 2 matrices with determinant one:: mbox{SL} 2(mathbb{R}) = left{ egin{bmatrix}a b c dend{bmatrix} : a,b,c,dinmathbb{R}mbox{ and }ad bc=1 ight}.It is a real Lie… … Wikipedia
N-group (finite group theory) — In mathematical finite group theory, an N group is a group all of whose local subgroups (that is, the normalizers of nontrivial p subgroups) are solvable groups. The non solvable ones were classified by Thompson during his work on finding all the … Wikipedia
Alternating group — In mathematics, an alternating group is the group of even permutations of a finite set. The alternating group on the set {1,..., n } is called the alternating group of degree n , or the alternating group on n letters and denoted by A n or Alt( n… … Wikipedia
Group of Lie type — In mathematics, a group of Lie type G(k) is a (not necessarily finite) group of rational points of a reductive linear algebraic group G with values in the field k. Finite groups of Lie type form the bulk of nonabelian finite simple groups.… … Wikipedia
Automorphisms of the symmetric and alternating groups — In group theory, a branch of mathematics, the automorphisms and outer automorphisms of the symmetric groups and alternating groups are both standard examples of these automorphisms, and objects of study in their own right, particularly the… … Wikipedia
Groupe De Type De Lie — En mathématiques, un groupe de type de Lie G(k) est un groupe (non nécessairement fini) de points rationnels d un groupe algébrique linéaire G à valeur dans le corps k. La classification des groupes simples finis montre que les groupes de types… … Wikipédia en Français

Outer automorphism group — In mathematics, the outer automorphism group of a group G is the quotient Aut(G) / Inn(G), where Aut(G) is the automorphism group of G and Inn(G) is the subgroup consisting of inner automorphisms. The outer automorphism group is usually … Wikipedia
Monstrous moonshine — In mathematics, monstrous moonshine, or moonshine theory, is a term devised by John Horton Conway and Simon P. Norton in 1979, used to describe the (then totally unexpected) connection between the monster group M and modular functions… … Wikipedia
