On root categories of finite-dimenisonal algebras
Changjian Fu
For any finite-dimensional algebra over a field with finite global dimension, we investigate the root category $\cR_A$ as the triangulated hull of the 2-periodic orbit cate…

The Ringel--Hall Lie algebra of a spherical object
Changjian Fu, Dong Yang
For an integer , let $\cs_w$ be the algebraic triangulated category generated by a -spherical object. We determine the Picard group of $\cs_w$ and show that each orbit catego…
