Contractibility and total semi-stability conditions of Euclidean quivers
Yu Qiu, Xiaoting Zhang
We study the bounded derived category of an Euclidean quiver, or equivalently, that of coherent sheaves on a tame weighted projective line. We give a description of t…
Using H Filaments to Probe AGN Feedback in Galaxy Clusters
Yu Qiu, Tamara Bogdanovic, Yuan Li +1
Recent observations of giant ellipticals and brightest cluster galaxies (BCGs) provide tentative evidence for a correlation between the luminosity of the H emitting gas filamen…
Verdier quotients of Calabi-Yau categories from quivers with potential
Anna Barbieri, Yu Qiu
We study a class of triangulated categories obtained as Verdier quotients of 3-Calabi-Yau categories combinatorially described by quivers with potential from (decorated) marked sur…
Perverse schobers, stability conditions and quadratic differentials I
Merlin Christ, Fabian Haiden, Yu Qiu
We develop a unified approach for identifying spaces of stability conditions of triangulated categories arising from weighted marked surfaces with moduli spaces of quadratic differ…
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…
Salient Object Detection in Traffic Scene through the TSOD10K Dataset
Yu Qiu, Yuhang Sun, Jie Mei +2
Traffic Salient Object Detection (TSOD) aims to segment the objects critical to driving safety by combining semantic (e.g., collision risks) and visual saliency. Unlike SOD in natu…
