Abstract
We consider a domain wall network with the usual degrees of freedom, but model the interactions as being able to occur between defects with varying energy (mass) densities. To the usual evolution equations an extra term for these interactions is added, following similar work with cosmic strings. The network's scaling properties are then studied in detail, including their dependence in the parameter space, with the result that the curvature parameter is what determines the regime the network follows.
