AIR tilting subcategories of extended hearts
Jiaqun Wei, Yu Zhou
We introduce the notion of AIR tilting subcategories of extended hearts of -structures on a triangulated category associated with silting subcategories. This notion generalizes…

Decorated Marked Surfaces with vortices: Cluster braid group vs. braid twist group
Yu Qiu, Yu Zhou
Let be a marked surface with vortices (=punctures with extra symmetry). We study the decorated version , where the $\mathbb{Z…

Tilting theory for extended module categories
Yu Zhou
In extended hearts of bounded -structures on a triangulated category, we provide a Happel-Reiten-Smalo tilting theorem and a characterization for -torsion pairs. Applying the…
