71Zuckerman functor — This article is about the Zuckerman induction functor, which is not the same as the (Zuckerman) translation functor. In mathematics, a Zuckerman functor is used to construct representations of real reductive Lie groups from representations of… …
72Quaternion-Kähler symmetric space — In differential geometry, a quaternion Kähler symmetric space or Wolf space is a quaternion Kähler manifold which, as a Riemannian manifold, is a Riemannian symmetric space. Any quaternion Kähler symmetric space with positive Ricci curvature is… …
73Banach–Stone theorem — In mathematics, the Banach–Stone theorem is a classical result in the theory of continuous functions on topological spaces, named after the mathematicians Stefan Banach and Marshall Stone.tatement of the theoremFor a topological space X , let C… …
74Sl2-triple — In the theory of Lie algebras, an sl 2 triple is a triple of elements of a Lie algebra that satisfy the commutation relations between the standard generators of the special linear Lie algebra sl 2. This notion plays an important role in the… …

77Classical involution theorem — In mathematical finite group theory, the classical involution theorem of Aschbacher (1977a, 1977b, 1980) classifies simple groups with a classical involution and satisfying some other conditions, showing that they are mostly groups of Lie… …
78Dade isometry — In mathematical finite group theory, the Dade isometry is an isometry from class functions on a subgroup H with support on a subset K of H to class functions on a group G (Collins 1990, 6.1). It was introduced by Dade (1964) as a generalization… …
79Dense submodule — In abstract algebra, specifically in module theory, a dense submodule of a module is a refinement of the notion of an essential submodule. If N is a dense submodule of M, it may also be said it may alternatively be said that N ⊆ M is a… …
