Query: Cosmology with type-Ia supernovae   I review the use of type-Ia supernovae (SNe) for cosmological studies. After
briefly recalling the main features of type-Ia SNe that lead to their use as
cosmological probes, I briefly describe current and planned type-Ia SNe
surveys, with special emphasis on their physics reach in the presence of
systematic uncertainties, which will be dominant in nearly all cases.
