Web2 dagen geleden · Superrigidity results. Ionut Chifan, Michael Davis, Daniel Drimbe. In \cite {CDD22} we investigated the structure of -isomorphisms between von Neumann algebras associated with graph product groups of flower-shaped graphs and property (T) wreath-like product vertex groups as in \cite {CIOS21}. In this follow-up we continue the structural … WebIonut Chifan; Affiliation: Department of Mathematics, 1326 Stevenson Center, Vanderbilt University, Nash- ville, Tennessee 37240 – and – Institute of Mathematics of the … WebIonut Chifan and Sayan Das Abstract On page 43 in [ Po83 ] Sorin Popa asked whether the following property holds: If ω is a free ultrafilter on N and R 1 ⊆ R is an irreducible inclusion of hyperfinite II 1 factors such that R ′ ∩ R ω ⊆ R ω 1 does it follows that R 1 = R ? central school chichester uk
