Query: A Note on the Equality of Algebraic and Geometric D-Brane Charges in WZW
  Models   The algebraic definition of charges for symmetry-preserving D-branes in
Wess-Zumino-Witten models is shown to coincide with the geometric definition,
for all simple Lie groups. The charge group for such branes is computed from
the ambiguities inherent in the geometric definition.
