摘要 本文主要研究了三角范畴在Abel化过程中torsion理论的保持问题.利用三角范畴的coherent函子范畴是Abel范畴,证明了T的coherent函子范畴A(T)是A(D)的thick子范畴;若(X,Y)是D的torsion理论,且D=X*Y的扩张是可裂的,那么(A(X),A(Y))是A(D)的torsion理论. The preserving problems of torsion theory during the course of the Abelianizationof triangulated categories are studied. By using the conclusion that the coherent functor categoryof triangulated category is an Abelian category, it is shown that the coherent functor categoryA(T) of T is a thick subcategory of A(D). If (Af, 32) is a torsion theory of 79 and the extension ofA' by y is split, we prove that (.A(X), A(y)) is a torsion theory of A(D).
