The Work of Harish-Chandra

Harish-Chandra was awarded the Wolf Prize in Mathematics in 1974 for his groundbreaking work on representation theory.

Harish-Chandra's Theorem is a fundamental result in representation theory that provides a complete classification of the irreducible representations of a semisimple Lie group.

Harish-Chandra's work primarily focused on semisimple, compact, and reductive Lie groups, while Abelian Lie groups were not a major area of his research.

Harish-Chandra's Integral Formula is a powerful tool for studying the characters of irreducible representations of semisimple Lie groups.

While Harish-Chandra made significant contributions to the study of discrete series representations, principal series representations, and Harish-Chandra modules, he did not introduce the concept of unitary representations.

Harish-Chandra's book 'Representation Theory of Semisimple Lie Groups' is a seminal work that provides a comprehensive treatment of the subject.

Roger Howe, David Kazhdan, and George Mackey were all students of Harish-Chandra, while Robert Langlands was not.

Harish-Chandra's Conjecture is a deep and challenging problem in representation theory that has attracted considerable attention from mathematicians.

Harish-Chandra's research primarily focused on representation theory, automorphic forms, and harmonic analysis, while number theory was not a major area of his work.

Harish-Chandra's Character Formula is a fundamental result that provides a deep connection between the representation theory of semisimple Lie groups and their Casimir operators.

Harish-Chandra primarily focused on irreducible representations and infinite-dimensional representations, while reducible representations were not a major area of his research.

Harish-Chandra's Weyl Group Formula is a powerful tool for studying the characters of irreducible representations of semisimple Lie groups.

While Harish-Chandra made significant contributions to the study of discrete series representations, principal series representations, and Harish-Chandra modules, he did not introduce the concept of cuspidal representations.

Harish-Chandra's Flag Manifold Formula is a deep and beautiful result that connects the representation theory of semisimple Lie groups to the geometry of their flag manifolds.
