Topics in descriptive set theory related to equivalence relations, complex borel and analytic sets
<p>The purpose of this doctoral dissertation is first to show that certain kinds of invariants for measures, self-adjoint and unitary operators are as far from complete as possible and second to give new natural examples of complex Borel and analytic sets originating from Analysis and Geome...
