Borel Spaces
(1752K, pdf)

ABSTRACT.   A detailed exposition of G.W. Mackey's theory of Borel 
spaces (standard, substandard, analytic), based on results 
in Chapter 9 of Bourbaki's General Topology. Appended 
are five informal lectures on the subject (given at the 
CIMPA/ICPAM Summer School, Nice, 1986), sketching the 
connection between Borel spaces and representations 
of operator algebras.
