报告摘要：
Let (F ',F,F'') be a comparison of left recollements of triangulated categories such that F' and F ''are equivalences. We prove that if F is full then F is an equivalence; and on the other hand, 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.
