Room: 002 Math. Sci. Building

Abstract: I start with my structural results on arbitrary free product von Neumann algebras, and then present new results in the direction, which in part strengthen Dykema's previous result on the centralizers of certain free product von Neumann algebras in the prospective perfect form. The key is a simple observation partly based upon the so-called Takesaki(!) duality. This finishes my initial plan of research, which dates back to my graduate school days. This line of my research was partly influenced by Takesaki's many treatises including his CBMS monograph.
