Covariant Lie Derivatives and (Super-)Gravity
Grigorios Giotopoulos
The slightly subtle notion of covariant Lie derivatives of \textit{bundle-valued} differential forms is crucial in many applications in physics, notably in the computation of conse…
Field Theory via Higher Geometry II: Thickened Smooth Sets as Synthetic Foundations
Grigorios Giotopoulos, Hisham Sati
This is the second in a series of papers that aim to develop rigorous and most encompassing foundations for field theory, where in the first installment, we laid out the natural fo…
Field Theory via Higher Geometry I: Smooth Sets of Fields
Grigorios Giotopoulos, Hisham Sati
Most modern theoretical considerations of the physical world suggest that nature is: (1) field-theoretic, (2) smooth, (3) local, (4) gauged, (5) containing fermions, and (6) non-pe…
Sheaf Topos Theory: A powerful setting for Lagrangian Field Theory
Grigorios Giotopoulos
We provide an introductory exposition to the sheaf topos theoretic description of classical field theory motivated by the rigorous description of both the variational ca…
