Key Points

The research aims to understand the effects of a time-variable cosmological constant on the mass density associated with scalar fields during inflation.
Analyzed the potential V(φ) of a scalar field with a power-law tail at large φ.
Examined the consequences of a time-variable mass density ρphi_ in cosmological models.
Identified that ρphi_ behaves like a cosmological constant that decreases more slowly than matter and radiation densities.
Proposed that an appreciable ρphi_ could reconcile low dynamical estimates with negligible space curvature.
