Abstract
We show that, for a Noetherian algebraic stack with quasi-affine diagonal , the stable -category of quasi-coherent sheaves on is dualizable if and only if the reduced identity component of the stabilizer of at every geometric point of positive characteristic is a torus. Along the way, we show that this condition on stabilizers is also equivalent to an array of other categorical conditions of interest.
