 目:Integral Hodge conjecture and beyonds

  要:Hodge conjecture predicts when a rational cohomology class is the fundamental class of an algebraic cycle. In recent years, there has been lots of interest in understanding which integral cohomology class comes from the fundamental class of an algebraic cycle. I will talk about examples, counterexamples, and some ideas lying behind these.
