Abstract
We calculate the ultrarelativistic Bose-Einstein condensation temperature of a complex scalar field with weak $\ensuremath{\lambda}({\ensuremath{\Phi}}^{\ifmmode\dagger\else\textdagger\fi{}}\ensuremath{\Phi}{)}^{2}$ interaction. We show that at high temperature and finite density we can use dimensional reduction to produce an effective three-dimensional theory which then requires nonperturbative analysis. For simplicity and ease of implementation we illustrate this process with the linear delta expansion.
