Abstract
It is argued that D-brane charge takes values in K-homology. For smooth man ifolds with spin structure, this could explain why the phase factor Omega ( x) calculated with a D-brane state x in IIB theory appears in Diaconescu, M oore and Witten's computation of the partition function of IIA string theor y.
