On Conjugacy of Subalgebras in Graph $C^{\ast }$-Algebras. II

Tomohiro Hayashi, Jeong Hee Hong, Wojciech Szymański

We apply a method inspired by Popa's intertwining-by-bimodules technique to investigate inner conjugacy of MASAs in graph $C^{\ast }$-algebras. First we give a new proof of non-inner con…
