Query: Imaginaries and invariant types in existentially closed valued
  differential fields   We answer two open questions about the model theory of valued differential
fields introduced by Scanlon. We show that they eliminate imaginaries in the
geometric language introduced by Haskell, Hrushovski and Macpherson and that
they have the invariant extension property. These two result follow from an
abstract criterion for the density of definable types in enrichments of
algebraically closed valued fields. Finally, we show that this theory is
metastable.
