Titre Entropy of an operator
Horaire16:00 à 18:00
RésumeWe extend the concept of the measure entropy from the group of automorphisms of a measure space to the group of unitary operators on a Hilbert space. Our main motivations concern formalization of the idea of quantum chaos. The key ingredient of our construction is a (probably) new concept from functional analysis, the mu-norm of a (bounded) operator on a Hilbert space.
