Geometric Foundations of Classical Yang-mills Theory

چکیده

We analyze the geometric foundations of classical YangMills theory by studying the relationships between internal relativity, locality, global/local invariance, and background independence. We argue that internal relativity and background independence are the two independent defining principles of Yang-Mills theory. We show that local gauge invariance – heuristically implemented by means of the gauge argument – is a direct consequence of internal relativity. Finally, we analyze the conceptual meaning of BRST symmetry in terms of the invariance of the gauge fixed theory under general local gauge transformations.

On the foundations and necessity of classical gauge invariance

We argue that, ideally, the ways to measure magnitudes in non-quantum theories of physics (spacetime, field theory), limit drastically their possible mathematical models. In particular, gauge invariance in the Yang-Mills framework, is a necessity of our way of measuring rather than an a priori imposition on symmetry. A general postulational basis for the geometric aspects of classical field the...

Gauge Theory in Two Dimensions: Topological, Geometric and Probabilistic Aspects

Two dimensional Yang-Mills theory has proved to be a surprisingly rich model, despite, or possibly because of, its simplicity and tractability both in classical and quantum forms. The purpose of this article is to give a largely self-contained introduction to classical and quantum Yang-Mills theory on the plane and on compact surfaces, along with its relationship to ChernSimons theory, illustra...

Twistor actions for non-self-dual fields; a new foundation for twistor-string theory

Twistor space constructions and actions are given for full Yang-Mills and conformal gravity using almost complex structures that are not, in general, integrable. These are used as the basis of a derivation of the twistor-string generating functionals for tree level perturbative scattering amplitudes of Yang-Mills and conformal gravity. The derivation follows by expanding and resumming the class...

Lectures on the Foundations of QCD

The manuscript presents the lecture notes of the course on the foundations of QCD given by the author for the graduate students of ITEP in the Spring of 1998. The following subjects are discussed: 1. Yang–Mills fields as connections on the principal fiber bundle. 2. Classical solutions in Minkowski and Euclidean space–time. 3. Path integrals in quantum mechanics and field theories. 4. Gauge sys...

Yang–mills Configuration Space

The geometric description of Yang--Mills theories and their configuration space M is reviewed. The presence of singularities in M is explained and some of their properties are described. The singularity structure is analyzed in detail for structure group SU(2). This review is based on [30]. 1 Yang--Mills theory and geometry Even more than fourty years after the seminal paper of Yang andMills on...
