Projectively Wakamatsu Tilting Modules over One-Point Extensions

Dajun Liu, Jiaxuan Feng, Hanpeng Gao

Let $\Gamma =\Lambda [M]$ be the one-point extension of an algebra $\Lambda$ by a $\Lambda$-module $M$. We establish a method to lift projectively Wakamatsu tilting (PWT) modules from $\mathrm{mod}\Lambda$ to…
