| Abstract: | Let A be a separable nuclear C
+ algebra with unit. Let  be a closed two-sided ideal in A. A relative K homology group K
0(A,) is defined. Closely related are topological definitions of properly supported K homology and of compactly supported relative K homology. Applications are to indices of Toeplitz operators and existence of coercive boundary conditions for elliptic differential operators. |
| Keywords: | K homology C* algebra elliptic operator C
