Query: On the definition and K-theory realization of a modular functor   We present a definition of a (super)-modular functor which includes certain
interesting cases that previous definitions do not allow. We also introduce a
notion of topological twisting of a modular functor, and construct formally a
realization by a 2-dimensional topological field theory valued in twisted
K-modules. We discuss, among other things, the N=1-supersymmetric minimal
models from the point of view of this formalism.
