PreprintThe \(\mathbb{F}_2\)-cohomology rings of 3-manifoldsJonathan A. HillmanAbstractWe give a new argument for the characterization of the cohomology rings of closed 3-manifolds with coefficients \(\mathbb{F}_2\), first given by M. M. Postnikov (in terms of intersection rings) in 1948. Keywords: 3-manifold, cohomology ring, mod-(2) coefficients.AMS Subject Classification: Primary 57M45.
