SN Light curves properties
B. Leibundgut
The supernova light curves are an essential ingredient for the
normalisation of the peak luminosity and the accurate distance
determinations. Yet, there are substantial problems with the application
of these normalisations. I will present some of the problems and try
to show how colour information can contribute to our understanding
of the influence of dust on the cosmological measurement.
