Harish Chandra Verma (born 3 April 1952), popularly known as HCV, is an Indian experimental physicist, author and emeritus professor of the Indian Institute of Technology Kanpur. In 2021, he was awarded the Padma Shri , the fourth highest civilian award, by the Government of India for his contribution to Physics Education. [ 1 ]
The Verma module is one particular such highest-weight module, one that is maximal in the sense that every other highest-weight module with highest weight is a quotient of the Verma module. It will turn out that Verma modules are always infinite dimensional; if λ {\displaystyle \lambda } is dominant integral, however, one can construct a ...
Harish-Chandra Mehrotra was born in Kanpur. [7] He was educated at B.N.S.D. College, Kanpur and at the University of Allahabad. [8] After receiving his master's degree in physics in 1940, he moved to the Indian Institute of Science, Bangalore for further studies under Homi J. Bhabha.
In mathematics, the Harish-Chandra isomorphism, introduced by Harish-Chandra (), is an isomorphism of commutative rings constructed in the theory of Lie algebras.The isomorphism maps the center (()) of the universal enveloping algebra of a reductive Lie algebra to the elements () of the symmetric algebra of a Cartan subalgebra that are invariant under the Weyl group.
The original proof of Harish-Chandra was a long argument by induction. [6] [7] [52] Anker (1991) found a short and simple proof, allowing the result to be deduced directly from versions of the Paley-Wiener and spherical inversion formula. He proved that the spherical transform of a Harish-Chandra Schwartz function is a classical Schwartz function.
In mathematics, specifically in the representation theory of Lie groups, a Harish-Chandra module, named after the Indian mathematician and physicist Harish-Chandra, is a representation of a real Lie group, associated to a general representation, with regularity and finiteness conditions.
Harish-Chandra [4] defined the Eisenstein integral by (:::) = () (() ())where: x is an element of a semisimple group G; P = MAN is a cuspidal parabolic subgroup of G; ν is an element of the complexification of a
The Verma module is called singular, if there is no dominant weight on the affine orbit of λ. In this case, there exists a weight λ ~ {\displaystyle {\tilde {\lambda }}} so that λ ~ + δ {\displaystyle {\tilde {\lambda }}+\delta } is on the wall of the fundamental Weyl chamber (δ is the sum of all fundamental weights ).
