    Non-renormalization theorems without supergraphs: The Wess-Zumino model

    Get PDF
    The non-renormalization theorems of chiral vertex functions are derived on the basis of an algebraic analysis. The property, that the interaction vertex is a second supersymmetry variation of a lower dimensional field monomial, is used to relate chiral Green functions to superficially convergent Green functions by extracting the two supersymmetry variations from an internal vertex and transforming them to derivatives acting on external legs. The analysis is valid in the massive as well as in the massless model and can be performed irrespective of properties of the superpotential at vanishing momentum.Comment: 20 pages, Latex, added acknowledgment

    The Role of Cognitive Differentiation in Conceptual Systems Theory

    Get PDF
    A cognitive approach to theory and research in personality proposes that individuals develop relatively enduring cognitive schemas for experiencing and organizing their .social world. Cognitive schemas are templates through which information is filtered or transformed. It may be understood that cognitive personality theory emphasises the structure of cognition rather than its content. Such an emphasis is based on the assumption that structural variables are relatively enduring and invariant across situations, whereas the content of personality is expected to fluctuate markedly. Cognitive personality theory should provide the researcher with an efficient basis for describing the actions of a person and lead to a more accurate prediction of his/her behavior (Scott, 1963)

    On the Baxterisation of Braid Group Representations of Rational Conformal Field Theories

    Get PDF
    We discuss aspects of Coulomb gas representations of rational conformal field theories which might be useful for the Baxterisation of braid group representations appearing in this context.Trigonometric solutions of the Yang-Baxter equations emerging from one-component Coulomb gases with underlying quantum group SU(2)_q are constructed explicitly

    An Algorithm for the Microscopic Evaluation of the Coefficients of the Seiberg-Witten Prepotential

    Get PDF
    A procedure, allowing to calculate the coefficients of the SW prepotential in the framework of the instanton calculus is presented. As a demonstration explicit calculations for 2, 3 and 4- instanton contributions are carried out.Comment: LaTeX, 23 pages; typos are corrected, determinant formula is simplifie
