Converse characterization of abelian duality spaces via the Albanese map
Converse characterization of abelian duality spaces via the Albanese map
Let be an -dimensional smooth complex quasi-projective variety with proper Albanese map
An abelian duality space of dimension is a space whose cohomology with coefficients in the group ring of its first homology is concentrated in degree and is nonzero there. Converse conjecture. is an abelian duality space of dimension if and only if is semi-small and is homotopy equivalent to a finite -dimensional CW complex. The theorem preceding this conjecture proves that the abelian-duality property follows under the stated geometric conditions in one direction; the conjecture asserts the converse as well, but the source gives no resolution.
