The authors' main claim We develop a velocity-dependent one-scale model for the evolution of domain wall networks in flat expanding or collapsing homogeneous and isotropic universes with an arbitrary number of spatial dimensions, finding the corresponding scaling laws in frictionless and friction dominated regimes.

We develop a velocity-dependent one-scale model for the evolution of domain wall networks in flat expanding or collapsing homogeneous and isotropic universes with an arbitrary number of spatial dimensions, finding the corresponding scaling laws in frictionless and friction dominated regimes. We also determine the allowed range of values of the curvature parameter and the expansion exponent for which a linear scaling solution is possible in the frictionless regime.

We develop a velocity-dependent one-scale model for the evolution of domain wall networks in flat expanding or collapsing homogeneous and isotropic universes with an arbitrary number of spatial dimensions, finding the corresponding scaling laws in frictionless and friction dominated regimes. We also determine the allowed range of values of the curvature parameter and the expansion exponent for which a linear scaling solution is possible in the frictionless regime.

This has been achieved by resorting to the Velocity-dependent One-Scale (VOS) model [ref] to describe the cosmological evolution of their characteristic scale $L ≡σ/ρ=η^3/ρ$ — where $σ$, $η≡σ^1/3$ and $ρ$ are, respectively, the domain wall tension, their characteristic energy scale and the average energy density of the domain wall network — and root-mean-squared velocity $v̅$.
