Graded decorated marked surfaces: Calabi-Yau- categories of gentle algebras
Akishi Ikeda, Yu Qiu, Yu Zhou
Let be a graded marked surface. We construct a string model for Calabi-Yau- category , via the graded DM…
Many Turan exponents via subdivisions
Tao Jiang, Yu Qiu
Given a graph and a positive integer , the {\it Turán number} $\ex(n,H)$ is the maximum number of edges in an -vertex graph that does not contain as a subgraph. A rea…
Turan numbers of bipartite subdivisions
Tao Jiang, Yu Qiu
Given a graph , the Turán number is the largest number of edges in an -free graph on vertices. We make progress on a recent conjecture of Conlon, Janzer, and Le…
Decorated Marked Surfaces: Calabi-Yau categories and related topics
Yu Qiu
This is a survey on the project `Decorated Marked Surfaces', where we introduce the decoration on a marked surfaces , to study Calabi-Yau-2 (cluster) categories, Ca…
Topological structure of spaces of stability conditions and topological Fukaya type categories
Yu Qiu
This is a survey on two closely related subjects. First, we review the study of topological structure of `finite type' components of spaces of Bridgeland's stability conditions on…
Cluster exchange groupoids and framed quadratic differentials
Alastair King, Yu Qiu
We introduce the cluster exchange groupoid associated to a non-degenerate quiver with potential, as an enhancement of the cluster exchange graph. In the case that arises from an (u…
