Abstract

The paper provides a version of the rational Hodge conjecture for $\3\dg$ categories. The noncommutative Hodge conjecture is equivalent to the version proposed in \cite{perry2020integral} for admissible subcategories. We obtain examples of evidence of the Hodge conjecture by techniques of noncommutative geometry. Finally, we show that the noncommutative Hodge conjecture for smooth proper connective $\3\dg$ algebras is true.

非交换霍奇猜想

本文给出了$\3\dg$类的有理Hodge猜想的一个版本。非交换霍奇猜想等价于\cite{perry2020integral}中提出的关于可容许子范畴的版本。我们用非交换几何的方法得到了霍奇猜想的证据实例。最后，我们证明了光滑固有连接$\3\dg$代数的非交换Hodge猜想是成立的。
