H. Awata et al., CHARACTER AND DETERMINANT FORMULAS OF QUASIFINITE REPRESENTATION OF THE W-1+INFINITY ALGEBRA, Communications in Mathematical Physics, 172(2), 1995, pp. 377-400
We diagonalize the Hilbert space of some subclass of the quasifinite m
odule of the W-1+infinity algebra. States are classified according to
their eigenvalues for infinitely many commuting charges and the Young
diagrams. The parameter dependence of their norms is explicitly derive
d. The full character formulae of the degenerate representations are g
iven as summation of the bilinear combinations of the Schur polynomial
s.
