DESCRIPTION:[b]Speaker: Arne Hofmann[/b] (University of Göttingen) [nl][nl
 ]\n[b]Abstract:[/b][nl]\nIn 2000\, Brunetti and Fredenhagen built on the 
 causal perturbation theory of Epstein and Glaser to prove the renormalisa
 bility of scalar field theory on curved spacetimes. Their construction wa
 s criticized in subsequent publications by Hollands and Wald for failing 
 to satisfy local covariance. I will show that with appropriate modificati
 ons\, local covariance can be achieved in the Brunetti-Fredenhagen constr
 uction\, for distributions which resemble (classical) pseudodifferential 
 operators. The crucial feature of such distributions is the existence of 
 uniform asymptotic expansions.\n[nl]\n[nl]
