We study the quantum theory of the singular scalar field φ minimally coupled to gravity. In our approach, the scalar field is treated as a true quantum variable, while the scale factor a(t) is supposed to be classical. We evaluate the quantum average of the self-interaction potential V(φ) and use it in the modified differential equation for the Hubble parameter.
