Title: Generalized Benson-Carlson duality

Abstract: This paper deals with the landmark results of Benson and
Carlson's {\em Projective resolutions and Poincar\'{e} duality
complexes} Our goal is to provide some necessary background for that
work, and to prove some of their results in a more general setting. In
particular, we analyze what happens when we replace Benson and
Carlson's complex $C_\zeta$ with an arbitrary Yoneda extension
representing $\zeta$.
