Abstract. We summarize the discussion session on the variability of
Active Galactic Nuclei (AGN) held during the conference 'Star Forma-
tion through Time`. The presence of starbursts in type 2 AGN is now well
established, and the production of supernovae (SNe) is a natural conse-
quence of the age of their stellar populations. We review the possibility
of detecting SNe in some type 1 AGN.
1. Introduction
One of the favourite research topics of Roberto Terlevich in the last 20 years
has been to look for alternative ways to explain the phenomenology of AGN, in
particular quantifying the ability of star formation to power the nuclear emission.
Even before the presence of stars near the nuclei of some local AGN was rmly
established (Terlevich et al. 1990, Oliva et al. 1995, Heckman et al. 1997,
Gonzalez-Delgado et al. 1998 ...) Roberto and his collaborators were exploring
whether powerful massive starbursts could induce light variations that mimic
