Smoothness of a variety implies homological smoothness of DbCoh
I have been told that $D^bCoh(X)$ is homologically smooth if $X$ is a smooth variety, and I am trying to construct a proof. My background is not in algebra, so I apologize for elementary questions.
It ...

Is there a relation between Projection formula and Verdier duality
For suitable settings, $f\colon X\to Y$, $F,G$ we have projection formula and Verdier duality:
Projection formula: $Rf_!(F\otimes^\mathbb{L}f^{-1}G)\cong Rf_!F\otimes^{\mathbb{L}}G$
Verdier Duality:...
