关于相对导出范畴

On relative derived categories

J. Asadollahi, P. Bahiraei, R. Hafezi, R. Vahed

摘要:

本文主要研究与相对导出范畴概念有关的一些自然产生的问题。特别地,我们研究了包含相对导出范畴的子元素的不变量,通过证明Gorenstein导出范畴中AR-三角形的存在性推广了Happel的两个结果,给出了相对于Gorenstein投射模和Gorenstein内射模的相对导出范畴等价的情形,最后研究了反射函子下的子的Gorenstein导出范畴与它的象之间的关系.提供了一些有趣的应用程序。

英文摘要:

The paper is devoted to study some of the questions arises naturally in connection to the notion of relative derived categories. In particular, we study invariants of recollements involving relative derived categories, generalise two results of Happel by proving the existence of AR-triangles in Gorenstein derived categories, provide situations for which relative derived categories with respect to Gorenstein projective and Gorenstein injective modules are equivalent and finally study relations between the Gorenstein derived category of a quiver and its image under a reflection functor. Some interesting applications are provided.
