Abstract
Let A be a separable nuclear C+ algebra with unit. Let g{script} be a closed two-sided ideal in A. A relative K homology group K0(A,g{script}) 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.
