  • Sophus Lie—the precursor of the modern theory of Lie groups.
  • Wilhelm Killing, who discovered almost all central concepts and theorems on the structure and classification of semisimple Lie algebras.
  • Élie Cartan and is primarily concerned with developments that would now be interpreted as representations of Lie algebras, particularly simple and semisimple algebras.
  • Hermann Weyl the development of representation theory of Lie groups and algebras.


development of representation theory of Lie groups

  • 1913 Cartan spin representations
  • 19?? Weyl unitarian trick : Complete reducibility
  • Dynkin, The structure of semi-simple Lie algebras
    • amre,math.sco.transl.17

Coxeter-Dynkin diagrams

  • 1934, Coxeter, 'Discrete groups generated by reflections'
  • 1946, Dynkin, introduces 'simple roots' and the so-called Dynkin diagrams to classify simple Lie algebras
  • 1955, Tits, 'on certain classes of homogeneous spaces of Lie groups', Dynkin diagrams used today.

development of theory of linear algebraic groups

Bruhat and subsequence works

  • 1954 Bruhat decomposition, Bruhat on the representation theory of complex Lie groups
  • 1955 Chevalley [81,83] picked up on Bruhat decomposition immediately, and it became a basic tool in his work on the construction and classification of simple algebraic groups
  • 1956 Borel,“Borel subgroup” of G as a result of the fundamental work on linear algberaic groups
  • 1962 Jacques Tits, introduced BN-pair, develops the theory of groups with a $(B,N)$ pair where $B$ is for Borel, $N$ is the normalizer of a maximal torus contained in $B$
  • 1965 Tits, Bourbaki Seminar expose , introduced the Building


flag manifold and Borel subgroup

  • general linear group G by the isotropy subgroup B of a standard flag (say, the group of upper triangular nonsingular matrices)
  • connected maximal solvable subgroups became known as Borel subgroups, while the notion of flag manifold came to mean the quotient $G/B$

for an arbitrary connected reductive Lie group G and a Borel subgroup B
