Homotopy classes of gauge fields and the lattice
Claudio Meneses, José A. Zapata
For a smooth manifold , possibly with boundary and corners, and a Lie group , we consider a suitable description of gauge fields in terms of parallel transport, as groupoid h…

Observable currents in lattice field theories
José A. Zapata
Observable currents are spacetime local objects that induce physical observables when integrated on an auxiliary codimension one surface. Since the resulting observables are indepe…

Multisymplectic effective General Boundary Field Theory
Mona Arjang, José A. Zapata
The transfer matrix in lattice field theory connects the covariant and the initial data frameworks; in spin foam models, it can be written as a composition of elementary cellular a…
