Weight structures and t-structures on the triangulated category generated by a $\mathbb{P}$-object

Source abstract

$\mathbb{P}$-objects were introduced by Huybrechts and Thomas as a generalization of spherical objects. We classify the weight structures and t-structures on the triangulated category generated by a $\mathbb{P}^n[k]$-object in the sense of Krug. For $n=1$, this recovers the classification of weight structures and t-structures on the triangulated category generated by a spherical object due to Holm, Jorgensen and Yang. We also compute the Koszul-dual model of the triangulated category generated by a $\mathbb{P}^n[k]$-object.
