Abstract
The dynamics of the inflaton scalar field oscillating around a minimum of singular potentials in the expanding Universe is studied. Asymptotic formulas are obtained, describing the cosmological expansion at late times. The problem of stability of the considered oscillanions as well as a related phenomenon of field fragmentation are briefly discussed.
