Saskatc hewan\, Canada) as part of Functional analysis and operator algebras in At hens\n\n\nAbstract\nC*-algebras are studied through various tools and tech niques including their tensor products. There are several classes of tens or products that have been considered and studied extensively on C*-algebr as. We introduce a new class of such objects using the theory of complex i nterpolations on operator spaces. Our construction allows us to produce a continuum family of distinct tensor product of the reduced C*-algebras of nonamenable groups possessing both the rapid decay and Haagerup property. We will show that they are in fact in the form of a Brown-Guentner type C* -completion. As another application of our approach\, we provide a complet e answer to a question of Leptin and Poguntke from 1979 proving that a C*- algebra is rigidly symmetric if and only if it is type I. \n\nThis talk is based on a joint work with Hun Hee Lee (SNU) and Matthew Wiersma (U of Wi nnipeg).\n LOCATION:https://researchseminars.org/talk/AthensFAOA/59/ END:VEVENT END:VCALENDAR
