Erling Størmer : Positive linear maps on matrix algebras
Professor Emeritus Erling Størmer will turn 80 on November 2, and he will use this occasion to give a Colloquium Talk with tittle:
POSITIVE LINEAR MAPS ON MATRIX ALGEBRAS
Abstract: The first part of the talk will be an introduction to the theory of positive linear maps between matrix algebras, plus a few words on the operator algebra case. For the last 20 years, physicists working in quantum information theory have been active in the subject and I’ll devote the last half of the talk to a negative solution to a conjecture they had.
Coffee/tea and cakes will be served from 14.00 in the lunch room.
