Exotic fine moduli spaces of coherent sheaves .  "Algebraic cycles, sheaves, shtukas, and moduli; Impanga lecture notes", Trends in Mathematics, Birkhäuser (2008).
An exotic fine moduli space of sheaves is one that does not come from the theory of (semi-)stable sheaves. We will give several examples of exotic fine moduli spaces in this paper. Sometimes the corresponding sheaves will not be simple, contrary to stable sheaves.
