Abstract:  Very flat and contraadjusted modules naturally arise in Algebraic Geometry.  They were defined by Positselski
[arXiv:1209.2995]. We will summarize the main properties of these modules and of the corresponding class of sheaves.
We will define a mock homotopy category of projectives on a quasi-compact and semi-separated scheme by using very flat quasi-coherent sheaves and show the existence of a recollement among the different homotopy categories involved.
