Quasi root systems and vertex operator realizations of the Virasoro algebra
Boris Noyvert
A construction of the Virasoro algebra in terms of free massless two-dimensional boson fields is studied. The ansatz for the Virasoro field contains the most general unitary scalin…

Ramond sector of superconformal algebras via quantum reduction
Boris Noyvert
Quantum hamiltonian reduction of affine superalgebras is studied in the twisted case. The Ramond sector of "minimal" superconformal W-algebras is described in detail, the determina…
