Gauge natural field theories and applications to conservation laws 1
We review the notion of a gauge natural theory and we show in particular its role in implementing the very basic principles of any reasonable fundamental physical interaction. Conservation laws are investigated in this general framework by means of a skilful application of Nöther theorem together with the theory of superpotentials. Wess–Zumino model interacting with a gravitational fields is co...
متن کاملCovariant Field Equations, Gauge Fields and Conservation Laws from Yang-Mills Matrix Models
The effective geometry and the gravitational coupling of nonabelian gauge and scalar fields on generic NC branes in Yang-Mills matrix models is determined. Covariant field equations are derived from the basic matrix equations of motions, known as Yang-Mills algebra. Remarkably, the equations of motion for the Poisson structure and for the nonabelian gauge fields follow from a matrix Noether the...
متن کاملGauge Gravity and Conservation Laws in Higher Order Anisotropic Spaces
We propose an approach to the theory of higher order anisotropic field interactions and curved spaces (in brief, ha–field, ha–interactions and ha–spaces). The concept of ha–space generaliSes various types of Lagrange and Finsler spaces and higher dimension (Kaluza–Klein) spaces. This work consists from two parts. In the first we outline the theory of Yang–Mills ha–fields and two gauge models of...
متن کاملThe gauge theory of dislocations: conservation and balance laws
We derive conservation and balance laws for the translational gauge theory of dislocations by applying Noether’s theorem. We present an improved translational gauge theory of dislocations including the dislocation density tensor and the dislocation current tensor. The invariance of the variational principle under the continuous group of transformations is studied. Through Lie’s-infinitesimal in...
متن کاملVariational Tricomplex, Global Symmetries and Conservation Laws of Gauge Systems
Using the concept of variational tricomplex endowed with a presymplectic structure, we formulate the general notion of symmetry. We show that each generalized symmetry of a gauge system gives rise to a sequence of conservation laws that are represented by onshell closed forms of various degrees. This extends the usual Noether’s correspondence between global symmetries and conservation laws to t...
