Generalized bc-systems based on Hermitian vector bundles
نویسنده
چکیده
A generalized bc-system associated to a Hermitian vector bundle over a Riemann surface is introduced in close analogy to the usual rank one case. Some of the geometric analogies to the well-known case are studied. In particular, if there are no zero-modes, the \nonabelian" theta divisor appears. In the general case where zero-modes exist, it seems to be more diicult to nd a natural description. It is discussed in detail why no such system exists in low genus, that is on the Riemann sphere and on elliptic curves.

On the correlation functions of the vector bundlegeneralization of the bc - systemMatthias
It is shown that the determinants of the correlation functions of the generalized bc-system introduced recently are given as pullbacks of the non-abelian theta divisor. The usual bc-system appearing in bosonic string theory 1;2 is very well understood 1?4 and has also been considered in a rigorous algebro-geometric way by Raina 5;6. Assuming some natural physical axioms, Raina showed the existe...
متن کاملHermitian-einstein Metrics for Vector Bundles on Complete Kähler Manifolds
In this paper, we prove the existence of Hermitian-Einstein metrics for holomorphic vector bundles on a class of complete Kähler manifolds which include Hermitian symmetric spaces of noncompact type without Euclidean factor, strictly pseudoconvex domains with Bergman metrics and the universal cover of Gromov hyperbolic manifolds etc. We also solve the Dirichlet problem at infinity for the Hermi...
متن کاملA note on families of bc-systems of higher rank
We consider a special family of bc-systems of higher rank and discuss some properties of its associated anomaly. The bc-system rst appeared in bosonic string theory as a gauge xing ghost system and plays a central role 1], in particular in the path-integral approach to scattering amplitudes (see 2, 3] and the extensive list of references therein). In this approach the nal expressions are nite d...
متن کاملComplex Line Bundles over Simplicial Complexes and their Applications
Discrete vector bundles are important in Physics and recently found remarkable applications in Computer Graphics. This article approaches discrete bundles from the viewpoint of Discrete Differential Geometry, including a complete classification of discrete vector bundles over finite simplicial complexes. In particular, we obtain a discrete analogue of a theorem of André Weil on the classificati...
متن کاملArithmetic Characteristic Classes of Automorphic Vector Bundles
We develop a theory of arithmetic characteristic classes of (fully decomposed) automorphic vector bundles equipped with an invariant hermitian metric. These characteristic classes have values in an arithmetic Chow ring constructed by means of differential forms with certain log-log type singularities. We first study the cohomological properties of log-log differential forms, prove a Poincaré le...
