Cup and cap products in intersection (co)homology
Greg Friedman, James McClure
We construct cup and cap products in intersection (co)homology with field coefficients. The existence of the cap product allows us to give a new proof of Poincare duality in inters…

The symmetric signature of a Witt space
Greg Friedman, James McClure
Witt spaces are pseudomanifolds for which the middle-perversity intersection homology with rational coefficients is self-dual. We give a new construction of the symmetric signature…
