Beyond Eckmann-Hilton: Commutativity in Higher Categories
We show that in a weak globular omega-category, all composition operations are equivalent and commutative for cells with sufficiently degenerate boundary, which can be considered a …
Zeta-regularized Lattice Field Theory with Lorentzian background metrics
Lattice field theory is a very powerful tool to study Feynman's path integral non-perturbatively. However, it usually requires Euclidean background metrics to be well-defined. On …
