	THE CALKIN ALGEBRA IS NOT COUNTABLY HOMOGENEOUS ILIJAS FARAH AND ILAN HIRSHBERG Abstract. We show that the Calkin algebra is not countably homogeneous, in the sense of continuous model theory. We furthermore show that th DocID: 1vnHK - View Document
	ADDENDUM TO “ALL AUTOMORPHISMS OF THE CALKIN ALGEBRA ARE INNER” ILIJAS FARAH Abstract. The proof of my recent result that all automorphisms of the Calkin algebra are inner can be simplified by using a simple observat DocID: 1vlGI - View Document
