Finite group, representation of a: A homomorphism of a finite group $ G $ into the group of non-singular linear mappings of a vector space into itself over a field $ K $. The representation theory of finite groups is the most highly developed (and is a most ... (Mathematics) [76%] 2023-10-18
Representation theory of diffeomorphism groups: In mathematics, a source for the representation theory of the group of diffeomorphisms of a smooth manifold M is the initial observation that (for M connected) that group acts transitively on M.

Representation theory: Representation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces, and studies modules over these abstract algebraic structures. In essence, a representation makes an abstract algebraic object more ... (Branch of mathematics that studies abstract algebraic structures) [71%] 2023-12-16 [Representation theory]
Representation theory: A theory studying homomorphisms of semi-groups (in particular, groups), algebras or other algebraic systems into corresponding endomorphism systems of suitable structures. Most often one considers linear representations, i.e. (Mathematics) [71%] 2023-05-22
Finite-dimensional representation: A linear representation of a topological group in a finite-dimensional vector space. The theory of finite-dimensional representations is one of the most important and most developed parts of the representation theory of groups. (Mathematics) [66%] 2023-09-13
Finite group: A group with finitely many elements. The number of elements is called the order of the group. (Mathematics) [65%] 2023-10-17
Finite group: In abstract algebra, a finite group is a group whose underlying set is finite. Finite groups often arise when considering symmetry of mathematical or physical objects, when those objects admit just a finite number of structure-preserving transformations.

Emulation theory of representation: The emulation theory of representation postulates that there are multiple internal modeling circuitries in the brain referred to as emulators. These emulators mimic the input-output patterns of many cognitive operations including action, perception, and imagery. [61%] 2024-01-08 [Neuroscience]
