Query: Exceptional collections on isotropic Grassmannians   We introduce a new construction of exceptional objects in the derived
category of coherent sheaves on a compact homogeneous space of a semisimple
algebraic group and show that it produces exceptional collections of the length
equal to the rank of the Grothendieck group on homogeneous spaces of all
classical groups.
