支持$τ$ -在单点扩展上倾斜模块

Support $τ$-tilting modules over one-point extensions

Hanpeng Gao, Zongzhen Xie

摘要:

设$B$是$A$通过$A$ -模$X$的单点扩张代数.我们证明了每个支持$τ$ -倾斜$A$ -模都可以通过两种不同的方式扩展为支持$τ$ -倾斜$B$ -模.结果表明,存在一个不等式$$|\stilt B|\geqslant 2|\stilt A|.$$

英文摘要:

Let $B$ be the one-point extension algebra of $A$ by an $A$-module $X$. We proved that every support $τ$-tilting $A$-module can be extended to be a support $τ$-tilting $B$-module by two different ways. As a consequence, it is shown that there is an inequality $$|\stilt B|\geqslant 2|\stilt A|.$$
