Abstract: In this talk, I will propose a rational Hodge conjecture for smooth and proper small dg categories. Let X be a projective smooth variety. The Hodge conjecture of Per_(dg)(X) is equivalent to the classical rational Hodge conjecture of X. Using homological projective duality, more evidences of Hodge conjecture are obtained.
