From $τ$ -tilting to $τ_{2}$ -tilting via splitting tilting triples

Zhongyuan Wang, Haicheng Zhang, Tiwei Zhao

Let $(A, T, B)$ be a splitting tilting triple. We provide a construction of $τ_{2}$ -tilting $B$ -modules from $τ$ -tilting $A$ -modules. On the other hand, if $A$ is hereditary, by consid…

Silting subcategories and (co)torsion pairs associated to extended hearts

Liangwei Huang, Haicheng Zhang

We establish the poset isomorphisms between $(d + 1)$ -term silting subcategories, functorially finite $s$ -torsion pairs in the $d$ -extended heart, and hereditary complete cotorsion p…
