Semibricks and wide subcategories in extended module categories
Esha Gupta, Yu Zhou
For , we define semibricks and wide subcategories in the -extended hearts of bounded -structures on a triangulated category. We show that these semibricks are in bij…
A restricted model for the bounded derived category of gentle algebras
Esha Gupta
We present a restricted model for the bounded derived category of gentle algebras that encodes the indecomposable objects and positive extensions between them. The model is then us…
On -term silting objects, torsion classes, and cotorsion classes
Esha Gupta
For a finite-dimensional algebra over an algebraically closed field , it is known that the poset of -term silting objects in is isomo…
Euclidean algorithm for a class of linear orders
Shashwat Agrawal, Amit Kuber, Esha Gupta
Borrowing inspiration from Marcone and Montálban's one-one correspondence between the class of signed trees and the equimorphism classes of indecomposable scattered linear orders,…
On the stable radical of some non-domestic string algebras
Esha Gupta, Amit Kuber, Shantanu Sardar
We introduce the concept of a prime band in a string algebra and use it to associate to its finite bridge quiver. Then we introduce a new technique of `recursive systems' f…
