Towards modified bimetric theories within non-product spectral geometry

نویسندگان

چکیده

We discuss class of doubled geometry models with diagonal metrics. Based on the analysis known examples we formulate a hypothesis that supports treating them as modified bimetric gravity theories. Certain steps towards generic case are then performed.

Gauge Theories and Non-commutative Geometry

It is shown that a d-dimensional classical SU(N) Yang-Mills theory can be formulated in a d+ 2-dimensional space, with the extra two dimensions forming a surface with non-commutative geometry. In this paper we present an explicit proof for the case of the torus and the sphere. Quantum field theories on a non-commutative space-time have been studied for a long time [1]. Not surprisingly, the fir...

Spectral Geometry of Harmonic Maps into Warped Product Manifolds Ii

Let (Mn,g) be a closed Riemannian manifold and N a warped product manifold of two space forms. We investigate geometric properties by the spectra of the Jacobi operator of a harmonic map φ : M → N . In particular, we show if N is a warped product manifold of Euclidean space with a space form and φ,ψ : M → N are two projectively harmonic maps, then the energy of φ and ψ are equal up to constant ...

Towards effective topological gauge theories on spectral curves

We discuss a general approach to the nonperturbative treatment of quantum field theories based on existence of effective gauge theory on auxiliary ”spectral” Riemann curve. We propose an effective formulation for the exact solutions to some examples of 2d string models and 4d supersymmetric Yang-Mills theories and consider their natural generalizations. 1E-mail address: [email protected] 2E...

Gauge Theories Formulated on Surfaces with Non-commutative Geometry

We propose a formulation of d-dimensional classical SU(N) Yang-Mills theories on a d+2-dimensional space, with the extra two dimensions forming a surface with non-commutative geometry. This equivalence is valid in any finite order in the 1/N expansion.
