Lie group. In mathematics, a Lie group (pronounced / liː / LEE) is a group that is also a differentiable manifold, such that group multiplication and taking inverses are both differentiable.
Mar 24, 2017 · The "Lie" in Lie group means that these rotations can be done arbitrary small. Many small rotations makes for a big rotation. Lie groups capture the concept of "continuous symmetries". Share. Cite. Follow. answered Feb 20, 2011 at 23:42. Thomas Rot.

May 24, 2024 · A Lie group is a smooth manifold obeying the group properties and that satisfies the additional condition that the group operations are differentiable. This definition is related to the fifth of Hilbert's problems, which asks if the assumption of differentiability for functions defining a continuous transformation group can be avoided.

The main method of research in the theory of Lie groups is the infinitesimal method created by Lie. This method makes it possible to reduce the study of such a complicated object as a Lie group largely to the study of a purely algebraic object, a Lie algebra. To every Lie group $ G $ corresponds a Lie algebra $ L (G) $ , constructed as follows (see...
The existence of a global Lie group with a given real Lie algebra was proved in 1930 by Cartan. He also showed that a closed subgroup of a real Lie group is a Lie subgroup. Two types of Lie groups play a special role, namely: semi-simple and solvable ones (see Lie group, semi-simple; Lie group, solvable). A connected Lie group $ G $ is said to be s...
From the very beginning of the development of the theory of Lie groups it was clear that arbitrary Lie groups are close to linear Lie groups. Lie proved that in many cases Lie groups are locally isomorphic to linear Lie groups. The general theorem was obtained by I.D. Ado in 1935: Any Lie group is locally isomorphic to a linear Lie group (see ). At...
One of the main problems in the theory of Lie groups is that of classifying arbitrary connected Lie groups up to isomorphism. In the class of all locally isomorphic connected Lie groups that have the same Lie algebra there is a unique simply-connected Lie group $ G _{0} $ , and any Lie group $ G $ of this class is isomorphic to $ G _{0} / N $ where...
In the 1950-s a new step in the development of the theory of Lie groups was begun, which manifested itself, in particular, in the creation of the theory of algebraic groups (see Linear algebraic group). Earlier C. Chevalley (see ) had explained in detail the algebraic nature of the fundamental results of Lie group theory. The application of methods...
