    The inverse scattering matrix for the Schrödinger equation when the potentialq(x) ∈L 1 1 with a singular term

    When the potentialq(x) ∈L 1 1 with a singular term, the continuities of the scattering matrix of the Schrödinger equation are investigated. By means of the tr...

    The KN algebras and the geometrical quantization of heterotic strings

    By means of the KN algebra, the Virasoro and Kac-Moody superalgebras are extended on a genus-g Riemann surface. These are realized in the framework of heterotic superstring with the WZ term coupling the fiber bun...

    (2,0) Heterotic superstring with Wess-Zumino coupling

    By means of the identity operator and vertex operator technique, reparametrization invariance and BRST symmetry are proven for the heterotic string with Wess-Zumino term coupling the fiber bundle. The motion s...
