A proof of slow-roll local decay of inflaton fields in cosmology and axion fields in cold dark matter models
Matías Morales, Claudio Muñoz
We consider the long time behavior of solutions to scalar field models appearing in the theory of cosmological inflation (oscillons) and cold dark matter, in presence or absence of…
