Query: Quantum Corrections to Central Charges and Supersymmetric Casimir Energy
  in AdS$_3$/CFT$_2$   We study the Casimir energy of bulk fields in AdS$_3$ and its relation to
subleading terms in the central charge of the dual CFT$_2$. Computing both
sides of the standard CFT$_2$ relation $E=-c/12$ independently we show that
this relation is not necessarily satisfied at the level of individual bulk
supergravity states, but in theories with sufficient supersymmetry it is
restored at the level of bulk supermultiplets. Assuming only $(0,2)$
supersymmetry (or more), we improve the situation by relating quantum
corrections to the central charge and the supersymmetric Casimir energy which
in turn is related to an index. These relations adapt recent progress on the
AdS$_5$/CFT$_4$ correspondence to AdS$_3$/CFT$_2$ holography. We test our
formula successfully in several examples, including the $(0,4)$ MSW theory
describing classes of 4D black holes and the large $(4,4)$ theory that is
interesting for higher spin holography. We also make predictions for the
subleading central charges in several recently proposed $(2,2)$ dualities where
the CFT$_2$ is not yet well-understood.
