Query: F-theory and linear sigma models   We present an explicit method for translating between the linear sigma model
and the spectral cover description of SU(r) stable bundles over an elliptically
fibered Calabi-Yau manifold. We use this to investigate the 4-dimensional
duality between (0,2) heterotic and F-theory compactifications. We indirectly
find that much interesting heterotic information must be contained in the
`spectral bundle' and in its dual description as a gauge theory on multiple
F-theory 7-branes.
  A by-product of these efforts is a method for analyzing semistability and the
splitting type of vector bundles over an elliptic curve given as the sheaf
cohomology of a monad.
