An invariant for unbounded operators
(2006) In Proceedings of the American Mathematical Society 134(9). p.25932598 Abstract
 For a class of unbounded operators, a deformation of a Bott projection is used to construct an integervalued invariant measuring deviation of the noncommutative deformations from the commutative originals, and its interpretation in terms of Ktheory of C*algebras is given. Calculation of this invariant for specific important classes of unbounded operators is also presented.
