Gauge from holography and holographic gravitational observables

José A. Zapata

In a spacetime divided into two regions $U_{1}$ and $U_{2}$ by a hypersurface $Σ$ , a perturbation of the field in $U_{1}$ is coupled to perturbations in $U_{2}$ by means of the holographic…

Observable currents and a covariant Poisson algebra of physical observables

Homero G. Díaz-Marín, José A. Zapata

Observable currents are locally defined gauge invariant conserved currents; physical observables may be calculated integrating them on appropriate hypersurfaces. Due to the conserv…

Homotopy classes of gauge fields and the lattice

Claudio Meneses, José A. Zapata

For a smooth manifold $M$ , possibly with boundary and corners, and a Lie group $G$ , we consider a suitable description of gauge fields in terms of parallel transport, as groupoid h…
