MATHPHYS ANALYSIS SEMINAR

Speaker:
Lajos Molnár, University of Szeged and TU Budapest
Location: Online via Zoom
In this talk we give a survey of our recent works on different 'symmetries' of structures (algebraic and geometric) on positive definite cones in $C^*$-algebras. Among others, we present precise descriptions of various algebraic isomorphisms, mean preservers, surjective isometries, preservers of relative entropy related quantities, etc.
