Covariant and gauge-invariant linear scalar perturbations in multiple scalar field cosmologies
Artur Alho, Filipe C. Mena
We derive a set of equations monitoring the evolution of covariant and gauge-invariant linear scalar perturbations of Friedman-Lemaître-Robertson-Walker models with multiple intera…

The spherically symmetric Einstein-scalar field system with positive and vanishing cosmological constant: a comparison
João L. Costa
We review recent results concerning the spherically symmetric Einstein-scalar field system with positive cosmological constant. We do so by comparing with the classical results of…

Theory of intersecting loops on a torus
J. E. Nelson, R. F. Picken
We continue our investigation into intersections of closed paths on a torus, to further our understanding of the commutator algebra of Wilson loop observables in 2+1 quantum gravit…
