Three-Point Trace Positivity:Schatten Norm Compression and Interpolating Metrics

Trung Dung Vuong, Hiroyuki Osaka

Let be a finite tracial von Neumann algebra and set . We prove that $$ [\mathcal{K}_r(P_i,P_j)]_{i,j=1}^3\ge0, \qquad 1/…

Alternative-mean trace divergences: geometry, data processing, and barycenters

Trung Dung Vuong, Hiroki Shudo, Hiroyuki Osaka

Let be a nontrivial normalized operator monotone function and set . We introduce the alternative-mean trace functional $$ \altPhi_f(A,B) :=\Tr(…

Limit of iteration of the induced Aluthge transformations of centered operators

Hiroyuki Osaka, Takeaki Yamazaki

Aluthge transform is a well-known mapping defined on bounded linear operators. Especially, the convergence property of its iteration has been studied by many authors. In this paper…

Rokhkin inclusions with integer and non-integer index

H. Lee, H. Osaka, T. Teruya

We construct new examples of inclusions of unital $C\sp*$-algebras of index-finite type with the Rokhlin property motivated by a broader attempt to understand the range of such inc…
