The rational cohomology characterization of complex tori
The rational cohomology characterization of complex tori
Let be a compact Kähler manifold of complex dimension , and write for its rational cohomology algebra. The rational cohomology conjecture for complex tori. Then is a complex torus if and only if
Equivalently,
The preceding theorem establishes the analogous characterization using integral cohomology; the proposed strengthening replaces integral coefficients by rational, or equivalently complex, coefficients, and no resolution is supplied in the source.
