摘要
证明了三角范畴的recollement可以自然诱导其商范畴的recollement.特别地,得到类似于群同态第二基本定理的结果,即若u是三角范畴D的局部化(或余局部化)子范畴,v是u的三角满子范畴,则u/v是D/v的局部化(或余局部化)子范畴,并且有三角等价(D/v)/(u/v)(?)D/u.同理,对Abel范畴的recollement也有相应的结果.
The author proves that a recollement of triangulated categories can induce a recollement of quotient categories naturally.In particular,the second isomorphism theorem of triangulated category,which is just like that of group,is obtained,i.e.,if U is a localizing (resp.colocalizing) subcategory of D and V is a full triangulated subcategory of U,then U/V is a localizing(resp.colocalizing) subcategory of D/V.Moreover,there is a triangulated equivalence(D/V)/(U/V)≌D/U.For the case of recollement of abelian categories,there are some analogous results.
