Warm DBI inflation with constant sound speed
Abstract We study inflation with the Dirac–Born–Infeld (DBI) noncanonical scalar field in both the cold and warm scenarios. We consider the Anti-de Sitter warp factor $$f(\phi )=f_{0}/\phi ^{4}$$ f(ϕ)=f0/ϕ4 for the DBI inflation and check viability of the quartic potential $$V(\phi )=\lambda \phi ^{...
