Query: Vector bundles and torsion free sheaves on degenerations of elliptic
  curves   In this paper we give a survey about the classification of vector bundles and
torsion free sheaves on degenerations of elliptic curves. Coherent sheaves on
singular curves of arithmetic genus one can be studied using the technique of
matrix problems or via Fourier-Mukai transforms, both methods are discussed
here. Moreover, we include new proofs of some classical results about vector
bundles on elliptic curves.
