Query: Quasi-coherent torsion sheaves, the semiderived category, and the
  semitensor product: Semi-infinite algebraic geometry of quasi-coherent
  sheaves on ind-schemes   We construct the semi-infinite tensor structure on the semiderived category
of quasi-coherent torsion sheaves on an ind-scheme endowed with a flat affine
morphism into an ind-Noetherian ind-scheme with a dualizing complex. The
semitensor product is "a mixture of" the cotensor product along the base and
the derived tensor product along the fibers. The inverse image of the dualizing
complex is the unit object. This construction is a partial realization of the
Semi-infinite Algebraic Geometry program, as outlined in the introduction to
arXiv:1504.00700.
