Abstract
For a class of unbounded operators, a deformation of a Bott projection is used to construct an integer-valued invariant measuring deviation of the non-commutative deformations from the commutative originals, and its interpretation in terms of K-theory of C*-algebras is given. Calculation of this invariant for specific important classes of unbounded operators is also presented.
