Sharp Bounds for Totally Invariant Cycles of Projective Varieties
Wentao Chang, Yujie Luo
Let be a smooth projective variety, an int-amplified endomorphism, and any ample line bundle on . We prove that, in every codimension, the total degree of pri…
On the -tilting finiteness and silting-discreteness of graded (skew-) gentle algebras
Wen Chang, Haibo Jin, Sibylle Schroll +1
This paper investigates finiteness conditions for gentle and skew-gentle algebras. First, we prove that a skew-gentle algebra is -tilting finite if and only if it is representat…
Log Calabi-Yau structure of algebaic varieties admitting a polarized endomorphism
Wentao Chang, De-Qi Zhang
Let be a normal projective variety admitting a polarized endomorphism , i.e., for some ample divisor and integer . Then Broustet and Gongyo proposed t…
Entropy of the Serre functor for partially wrapped Fukaya categories of surfaces with stops
Wen Chang, Alexey Elagin, Sibylle Schroll
We prove that the entropy of the Serre functor in the partially wrapped Fukaya category of a graded surface with stops is given by the function sending $t \in \mat…
Maximal rigid modules over a gentle algebra and applications to higher Auslander-Reiten theory
Wen Chang
We construct a bijective correspondence between the set of rigid modules over a gentle algebra and the set of admissible arc systems on the associated coordinated-marked surface. I…
Tilting-completion for gentle algebras
Wen Chang
It is demonstrated that any almost-tilting module over a gentle algebra is indeed partial-tilting, meaning it can be completed as a tilting module. Furthermore, such a module has a…
