DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/108/">Eq
 uivariant injectivity of crossed products</a>\nby Joeri De Ro (Vrije Unive
 rsiteit Brussel\, Belgium) as part of Quantum Groups Seminar [QGS]\n\n\nAb
 stract\nWe introduce the notion of a G-operator space\, which consists of 
 an action of a locally compact quantum group G on an operator space X\, an
 d we study the notion of G-equivariant injectivity for such an operator sp
 ace. We define a natural associated crossed product operator space X ⋊ G
 \, on which both the locally compact quantum group G and its dual act. We 
 completely characterise when these crossed products are equivariantly inje
 ctive with respect to these actions. We discuss how these results generali
 se and unify several recent results from the literature and we give some n
 ew applications.\n
