| « Fun splitting perturbations: adiabatic and entropy perturbations in the multi-fluid formalism » |

Karim Malik |
| I shall present recent work in which we used a gauge-invariant formalism to study the evolution of curvature perturbations on large scales in a Friedmann-Robertson-Walker universe filled by multiple interacting fluids. As a specific application I will use the recently proposed curvaton model, in which the curvaton decays into radiation. |
