On $d$ -term silting objects, torsion classes, and cotorsion classes

Esha Gupta

For a finite-dimensional algebra $I^$ over an algebraically closed field $K$ , it is known that the poset of $2$ -term silting objects in $K^{b} (proj I^)$ is iso…

Semibricks and wide subcategories in extended module categories

Esha Gupta, Yu Zhou

For $d \geq 1$ , we define semibricks and wide subcategories in the $d$ -extended hearts of bounded $t$ -structures on a triangulated category. We show that these semibricks are in bij…
