Canonical differential geometry of string backgrounds
Frederic P. Schuller, Mattias N. R. Wohlfarth
String backgrounds and D-branes do not possess the structure of Lorentzian manifolds, but that of manifolds with area metric. Area metric geometry is a true generalization of metri…
Covariant canonical quantization
Georg M. von Hippel, Mattias N. R. Wohlfarth
We present a manifestly covariant quantization procedure based on the de Donder--Weyl Hamiltonian formulation of classical field theory. This procedure agrees with conventional can…
Geometry of manifolds with area metric: multi-metric backgrounds
Frederic P. Schuller, Mattias N. R. Wohlfarth
We construct the differential geometry of smooth manifolds equipped with an algebraic curvature map acting as an area measure. Area metric geometry provides a spacetime structure s…
Cosmological constraints on a classical limit of quantum gravity
Damien A. Easson, Frederic P. Schuller, Mark Trodden +1
We investigate the cosmology of a recently proposed deformation of Einstein gravity, emerging from quantum gravity heuristics. The theory is constructed to have de Sitter space as…
