Query: Compact and weakly compact disjointness preserving operators on spaces
  of differentiable functions   A pair of functions defined on a set X with values in a vector space E is
said to be disjoint if at least one of the functions takes the value 0 at every
point in X. An operator acting between vector-valued function spaces is
disjointness preserving if it maps disjoint functions to disjoint functions. We
characterize compact and weakly compact disjointness preserving operators
between spaces of Banach space-valued differentiable functions.
