Description

Introduction ============ Pyflation is a Python package for calculating cosmological perturbations during inflationary expansion of the universe. Pyflation was created by Ian Huston (http://www.ianhuston.net) while at Queen Mary, University of London (http://www.qmul.ac.uk). Once installed the modules in the pyflation package can be used to run simulations of different scalar field models of the early universe. The main classes are contained in the cosmomodels module and include simulations of background fields and first order and second order perturbations. The sourceterm package contains modules required for the computation of the term required for the evolution of second order perturbations. The analysis package contains routines to calculate the first order First and Second order perturbations can be calculated for single field models but only first order perturbations can be evolved for multi-field models.
