    Bosonization techniques on algebraic curves and conformal field theories (1991)

    Notes: The bosonization of b-c systems is studied with conformal weight λ on Riemann surfaces in which the moduli space is parametrized by the branch points (algebraic curves). Besides being interesting in itself, the problem is related to perturbative string theories and to nonfree conformal field theories on the complex plane with the insertion of certain spin fields called the twist fields. The method of λ-differentials is proposed, which allows a complete treatment of the b-c systems on algebraic curves with local Abelian monodromy group. It can be nevertheless applied also to more general algebraic curves allowing the computation of the Green's functions and shedding some light about the structure of the twist fields in the general case. The connections between our formalism and the solutions of the Riemann monodromy problem, used to find out the conformal blocks of conformal field theories, are pointed out.

    Operator formalism for bosonic beta–gamma fields on general algebraic curves (1998)

    Notes: An operator formalism for bosonic β–γ system on arbitrary algebraic curves is introduced. The classical degrees of freedom are identified and their commutation relations are postulated. The explicit realization of the algebra formed by the fields is given in the Hilbert space equipped with a bilinear form. The construction is based on the "Gaussian" representation for β–γ system on the complex sphere [Alvarez-Gaumé et al., Nucl. Phys. B 311, 333 (1988)]. Detailed computations are provided for two- and four-point correlation functions. © 1998 American Institute of Physics.

    Bosonic field propagators on algebraic curves (2000)

    Notes: In this paper we investigate the theory of massless scalar fields on nondegenerate algebraic curves. The propagator is written in terms of the parameters appearing in the polynomial defining the curve. This provides an alternative to the language of theta functions. The main result is the derivation of a third kind differential normalized in such a way that its periods around the homology cycles are purely imaginary. All the physical correlation functions of the scalar fields can be expressed in terms of this object. This paper contains a detailed analysis of the techniques necessary to study field theories on algebraic curves. A simple expression of the scalar field propagator is found in a particular case, in which the algebraic curves have Zn internal symmetry and one of the fields is located at a branch point. © 2000 American Institute of Physics.

    Notes: Abstract In this Letter, the Maxwell field theory is considered on a closed and orientable Riemann surface of genus h $$$$ 1. The solutions of the Maxwell equations corresponding to nontrivial values of the first Chern class are explicitly constructed for any metric in terms of the prime form.

    Notes: Abstract In this paper a class of conformal field theories with nonabelian and discrete group of symmetry is investigated. These theories are realized in terms of free scalar fields starting from the simpleb-c systems and scalar fields on algebraic curves. The Knizhnik-Zamolodchikov equations for the conformal blocks can be explicitly solved. Besides the fact that one obtains in this way an entire class of theories in which the operators obey nonstandard statistics, these systems are interesting in exploring the connection between statistics and curved space-times, at least in the two dimensional case.
