Principal bundles and connections modelled by Lie group bundles

M Castrillón López, Á Rodríguez Abella - Geometriae Dedicata, 2023 - Springer
In this work, generalized principal bundles modelled by Lie group bundle actions are

Gauge reduction in covariant field theory

MC López, ÁR Abella - Journal of Physics A: Mathematical and …, 2024 - iopscience.iop.org
In this work, we develop a Lagrangian reduction theory for covariant field theories with
gauge symmetries. These symmetries are modeled by a Lie group fiber bundle acting …
