Approximation in the class of quasidiagonal operators

Marcoux, Laurent2010-01-072010-01-0719892010-01-07http://hdl.handle.net/1828/2043In this article we further investigate the class (ZTR) of "zero-trace" quasidiagonal operators defined by D. A. Herrero in [Her 2]. Also, partial results are obtained towards answering the question of whether or not quasidiagonal quasinilpotent operators are limits of block-diagonal nilpotent operators.entechnical reports (mathematics and statistics)Approximation in the class of quasidiagonal operatorsTechnical ReportDepartment of Mathematics and Statistics
