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