摘要: 结合t-结构的性质,讨论三角范畴的Ki-群与其t-结构Ki-群之间的关系,得到若t-结构是稳定t-结构,则三角范畴的Ki-群同构于其t-结构Ki- 群的直和(i=0,1)。

关键词: 三角范畴, t-结构, Ki-群

Abstract: Based on the properties of t-structure of a triangulated category, the paper discusses the relationship between the Ki-groups of t- structure of the triangulated category and Ki-groups of the triangulated category. Moreover, if t-structure is stable, it is shown that Ki- group of triangulated category is isomorphic to the direct sum of Ki- groups of t- structure.

Key words: triangulated category, t- structure, Ki- group
