报告摘要：We show that, for any dg algebra A, its perfect derived category can be realized respectively as an (enlarged) cluster category and a (shrunk) singularity category of certain differential bigraded algebras, generalizing results of Ikeda-Qiu and Happel/Hanihara-Iyama respectively. A direct equivalence between such a cluster category and singularity category is also given via relative Koszul duality. Finally, we show that these construction is compactible with taking orbit categories. This is a jo
