Inflation driven by causal heat flux

Research output: Contribution to journalArticlepeer-review


We find a simple inflationary solution in an inhomogeneous spacetime with heat flux. The heat flux obeys a causal transport equation, and counteracts the inflationary decrease of energy density. At late times, the heat flux tends to zero and thefluid approaches the equation of state p =–ρ.
