By Victor G Kac,Ashok K Raina,Natasha Rozhkovskaya

The first version of this publication is a suite of a chain of lectures given by way of Professor Victor Kac on the TIFR, Mumbai, India in December 1985 and January 1986. those lectures concentrate on the assumption of a optimum weight illustration, which matches via 4 assorted incarnations.

The first is the canonical commutation kinfolk of the endless dimensional Heisenberg Algebra (= oscillator algebra). the second one is the top weight representations of the Lie algebra gℓ of limitless matrices, besides their functions to the speculation of soliton equations, found through Sato and Date, Jimbo, Kashiwara and Miwa. The 3rd is the unitary optimum weight representations of the present (= affine Kac–Moody) algebras. those Lie algebras look within the lectures in connection to the Sugawara building, that is the most instrument within the examine of the fourth incarnation of the most concept, the speculation of the top weight representations of the Virasoro algebra. specifically, the booklet offers a whole facts of the Kac determinant formulation, the major lead to illustration concept of the Virasoro algebra.

The moment version of this e-book comprises, as its first half, the principally unchanged textual content of the 1st version, whereas its moment half is the gathering of lectures on vertex algebras, added by way of Professor Kac on the TIFR in January 2003. the elemental notion of those lectures used to be to illustrate how the main notions of the speculation of vertex algebras — resembling quantum fields, their basic ordered product and lambda-bracket, energy-momentum box and conformal weight, untwisted and twisted representations — simplify and make clear the structures of the 1st variation of the book.

This booklet could be very helpful for either mathematicians and physicists. To mathematicians, it illustrates the interplay of the main principles of the illustration conception of countless dimensional Lie algebras and of the speculation of vertex algebras; and to physicists, those theories are becoming a big portion of such domain names of theoretical physics as soliton concept, conformal box idea, the speculation of two-dimensional statistical types, and string theory.
