SUMMARY:OS Reelle Geometrie und Algebra: From Spectrahedra to Operator Sys
tems and Beyond
DESCRIPTION:Spectrahedra are the feasible sets of semidefinite programming
. They can be studied with methods from (real) algebraic geometry and conv
exity theory\, but much can also be learned by looking at their free (=non
commutative) extensions. These turn out be be almost the same as abstract
operator systems\, a well-studied notion from operator algebra. This conne
ction allows to transfer methods from operator algebra to semialgebraic ge
ometry and vice versa\, and leads to several interesting results. I will g
ive an introduction and overview about these topics\, and also explain how
they can be applied to questions from quantum information theory.\n\n
