    Gauge Symmetry in Background Charge Conformal Field Theory

    Get PDF
    We present a mechanism to construct four-dimensional charged massless Ramond states using the discrete states of a fivebrane Liouville internal conformal field theory. This conformal field theory has background charge, and admits an inner product which allows positive norm states. A connection among supergravity soliton solutions, Liouville conformal field theory, non-critical string theory and their gauge symmetry properties is given. A generalized construction of the SU(2) super Kac-Moody algebra mixing with the N=1 super Virasoro algebra is analyzed. How these Ramond states evade the DKV no-go theorem is explained.Comment: 20 pages, plain Tex, no figures, published versio

    The International Trade Commission: Potential Bias, Hold-Up, and the Need for Reform

    Get PDF
    The International Trade Commission (ITC) is an alternate venue for holders of U.S. patents to pursue litigation against infringing products produced abroad and imported to the United States. Because the ITC may only grant injunctive relief, it has awarded injunctions in situations where there may have been better and more efficient remedies to the infringement available through litigation in federal district court. The increased likelihood of injunctive relief bolsters the position of patent holders against a wide range of producers in royalty negotiations and can harm the end consumers through a process known as patent hold-up. There are currently sweeping and aggressive proposed reforms to reduce this harm to consumers. This iBrief suggests that the optimal reforms would not change the overall structure or scope of the ITC or its jurisdiction. Rather it would harmonize the substantive law, available defenses for respondents, and requirements for injunctive relief between ITC proceedings and litigation in federal district court

    The Weyl-Lanczos Equations and the Lanczos Wave Equation in 4 Dimensions as Systems in Involution

    Get PDF
    Using the work by Bampi and Caviglia, we write the Weyl-Lanczos equations as an exterior differential system. Using Janet-Riquier theory, we compute the Cartan characters for all spacetimes with a diagonal metric and for the plane wave spacetime since all spacetimes have a plane wave limit. We write the Lanczos wave equation as an exterior differential system and, with assistance from Janet-Riquier theory, we find that it forms a system in involution. This result can be derived from the scalar wave equation itself. We compute its Cartan characters and compare them with those of the Weyl-Lanczos equations.Comment: 18 pages, latex, no figures, references correcte
