%0 Journal Article %T Cup and cap products in intersection (co)homology %A Greg Friedman %A James McClure %J Mathematics %D 2011 %I arXiv %X 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 intersection (co)homology which is similar in spirit to the usual proof for ordinary (co)homology of manifolds. %U http://arxiv.org/abs/1106.4799v2
