This is about Witten's paper on "Mirror Manifolds
and Topological String Theory" , 9112056.
What is the best way to visualise powers, both
positive and negative, of the canonical line bundle?
What are the meanings of "K^1/2" and "K^-1"?
What is the relation between twisting the
fermions and rotational symmetry on the world sheet?
Why are the twisting the only ones we could do?
If we took the fermons to be sections of other powers
of the canonical line bundle on \sigma ( of course
tensored with the pullback of the tangent bundle on X)
what would be the effect on the world sheet? Would the
\sigma-model lagrangian remain invariant?
What is the relation between twisting with
different powers of the line bundle and the associated
U(1) gauge symmetry?
Does twisting the fermions change the spins of
the G+- in the superconformal algebra? What exactly is
the relation between changing the relevant bundles of
the fermions and the effect on the superconformal
algebra- for example the shift in the energy-momentum
tensor?
