On the normalizing algebra of a MASA in a II $_{1}$ Factor

Ionut Chifan

Let $A$ be a maximal abelian subalgebra (MASA) in a \II1 factor $M$ . Sorin Popa introduced an analytic condition that can be used to identify the normalizing algebra of $A$ in $M$ …

$C^{*}$ Estimates for Averaging Sums of Elements in the Thompson Group $F$

Ionut Chifan, Gabriel Picioroaga

In this paper we study the non-amenability question of the Thompson group $F$ from the $C^{*}$ algebra side. Using a characterization of amenability in this framework we set about…
