Introduction to Lie Groups
Lie Groups: Where Algebra Meets Geometry
Lie groups represent one of the most beautiful syntheses in mathematics, combining the algebraic structure of groups with the geometric structure of manifolds. They are fundamental in understanding symmetry in mathematics and physics.
What is a Lie Group?
A Lie group is a smooth manifold that is also a group, where the group operations (multiplication and inversion) are smooth maps. This simple definition leads to a rich theory with deep applications.
