A method to study critical behaviour in the non–integer space dimension $d$ is discussed. Calculations are performed on the base of the massive field theory equations (Callan–Symanzik equations) at fixed non–integer $d$. Quantitative characteristics of the critical behaviour of several popular models of statistical physics are reviewed.
