Classical Interactions for Tensionless Strings

Bjørn Jensen, Ulf Lindström

Using an ``action at a distance'' formulation we probe the possible classical interactions for tensionless strings, (the limit of the ordinary bosonic string.) We find $G_…

Manifest Duality in Born-Infeld Theory

Ingemar Bengtsson

Born-Infeld theory is formulated using an infinite set of gauge fields, along the lines of McClain, Wu and Yu. In this formulation electromagnetic duality is generated by a fully l…

Multiple Mellin-Barnes Integrals as Periods of Calabi-Yau Manifolds With Several Moduli

M. Passare, A. K. Tsikh, A. A. Cheshel

We give a representation, in terms of iterated Mellin-Barnes integrals, of periods on multi-moduli Calabi-Yau manifolds arising in superstring theory. Using this representation and…

On Chiral p-Forms

Ingemar Bengtsson, Astri Kleppe

Some aspects of chiral p-forms, in particular the obstruction that makes it hard to define covariant Green functions, are discussed. It is shown that a proposed resolution involvin…

Yang-Mills fields for Cosets

J. Grundberg, U. Lindstrom, M. Rocek

We consider theories with degenerate kinetic terms such as those that arise at strong coupling in super Yang-Mills theory. We compute the components of generalized su…

On N=2 low energy effective actions

F. Gonzalez-Rey, U. Lindstrom, M. Rocek +1

We propose a Wilsonian action compatible with special geometry and higher dimension N=2 corrections, and show that the holomorphic contribution F to the low energy effective action…

C-theorem for two dimensional chiral theories

Fiorenzo Bastianelli, Ulf Lindstrom

We discuss an extension of the -theorem to chiral theories. We show that two monotonically decreasing -functions can be introduced. However, their difference is a constant of…

Directly Interacting Massless Particles - a Twistor Approach

Andreas Bette

Twistor phase spaces are used to provide a general description of the dynamics of a finite number of directly interacting massless spinning particles forming a closed relativistic…
