Scalar field deformations of Lambda-CDM cosmology
Artur Alho, Claes Uggla
This paper treats nonrelativistic matter and a scalar field with a monotonically decreasing potential minimally coupled to gravity in flat Friedmann-Lemaître-Robertson-Walker c…

Global dynamics and asymptotics for monomial scalar field potentials and perfect fluids
Artur Alho, Juliette Hell, Claes Uggla
We consider a minimally coupled scalar field with a monomial potential and a perfect fluid in flat FLRW cosmology. We apply local and global dynamical systems techniques to a new t…
