目：Rational cohomology tori

间：08.20（星期四）, 10:00--11:00

点：数学院南楼913

要：Complex tori can be topologically characterized among compact Kähler manifolds by their integral cohomology ring. I will discuss the structure of compact Kähler manifolds whose rational cohomology ring is isomorphic to the rational cohomology ring of a torus and give some examples. This is joint work with Olivier Debarre and Marti Lahoz.
