设是一个正整数,是一个满足一定有限性条件的遗传阿贝尔范畴。本文从分次复形范畴定义了半导Ringel-Hall代数,并得到了半导Ringel-Hall代数的一个自然基。此外,我们还利用生成元和定义关系描述了半导Ringel-Hall代数。特别地,如果是奇整数,我们证明了奇周期相对导范畴的导Hall代数在广义半导Ringel-Hall代数中的嵌入.
Lettbe a positive integer andbe a hereditary abelian category satisfying some finiteness conditions. We define the semi-derived Ringel-Hall algebra offrom the categoryof-graded complexes and obtain a natural basis of the semi-derived Ringel-Hall algebra. Moreover, we describe the semi-derived Ringel-Hall algebra by the generators and defining relations. In particular, iftis an odd integer, we show that there is an embedding of the derived Hall algebra of the odd-periodic relative derived category in the extended semi-derived Ringel-Hall algebra.
