By Vladimir E. Nazaykinskiy, A. Yu. Savin, B. Yu. Sternin

The e-book offers with nonlocal elliptic differential operators. those are operators whose coefficients contain shifts generated via diffeomorphisms of the manifold on which the operators are outlined. the most aim of the examine is to narrate analytical invariants (in specific, the index) of such operators to topological invariants of the manifold itself. This challenge may be solved through sleek tools of noncommutative geometry. To make the e-book self-contained, the authors have integrated precious geometric fabric (C*-algebras and their K-theory, cyclic homology, etc.).

19 for operators in the standard module can be transferred without changes to the case of operators in arbitrarily countably generated Hilbert modules. This can be done by using the following theorem. 21. The following conditions are equivalent: 1. 20. 2. The operator F has left and right inverse operators modulo Λ-compact operators. 3. There exist decompositions M = M0 ⊕ M1 , N = N0 ⊕ N1 into direct sums of closed submodules, where the modules M1 and N1 are finitely generated, such that the operator F has a block-diagonal form with respect to these decompositions and the restriction F is an isomorphism.

Elliptic Operators over C ∗ -Algebras 44 Further, the index of the operator F satisfies the formula ind F = [M1 ] − [N1 ]. 2 Pseudodifferential Operators over Λ An important example of Λ-Fredholm operators is obtained if we consider elliptic pseudodifferential operators over the C ∗ -algebra Λ.

1 Operators of Order Zero First, we consider the case of operators of order zero in the spaces L2 . 3 Now we can in a rather standard way define nonlocal operators in the spaces of sections of noncommutative bundles. Note that the algebra C(M )Γ is naturally embedded in ΨΓ (M ) and is in this case realized by operators in the space L2 (M ), so that the group Γ acts by the shift operators T (g) and the subalgebra C(M ) ⊂ C(M )Γ acts by multiplication operators. We use this embedding to associate elements of the algebra C(M )Γ with their symbols treated as nonlocal pseudodifferential operators.
