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…
