Abstract
The velocity-dependent one-scale model of cosmic string network evolution is summarized. Treating the average string velocity as well as the characteristic lengthscale as dynamical variables, one can obtain a fully quantitative model, describing the complete evolution of a string network, including the prediction of previously unknown transient scaling regimes. We also discuss extensions to open, anisotropic and contracting universes, and the effect of radiation backreaction. Finally we discuss the calibration of the model parameters by comparing it to both Abelian-Higgs and Goto–Nambu simulations, in both a static and expanding backgrounds, and highlight the non-trivial fractal properties of cosmic strings.
