摘 要：Let (F′, F, F″) be a comparison of left recollements of triangulated categories such that F′ and F″ are equivalences. We construct a class of  examples via the derived categories of Morita rings, showing that there  really exists such a comparison (F′, F, F″) so that F is not an equivalence. This is in contrast to the case of a recollement. We also give a class of examples of left recollements of homotopy categories, which can not sit in recollements.
