Quasi-Sectorial Contractions

Mathematical Physics & Probability

Speaker: Valentin Zagrebnov, Université de la Méditerranée & Centre de Physique Théorique
Location: 1147 MSB
Start time: Wed, May 28 2008, 4:10PM

The notion of Quasi-Sectorial Contraction was invented few years ago in the framework of semigroups with m-sectorial generators. I discuss a relevance of this kind of contractions to the theory of operator-norm approximations of strongly continuous semigroups.
