Derived dimension via τ-tilting theory
Yingying Zhang
Comparing the bounded derived categories of an algebra and of the endomorphism algebra of a given support τ-tilting module, we find a relation between the derived dimensions of an…
Residue formula for an obstruction to Coupled Kähler-Einstein metrics
Akito Futaki, Yingying Zhang
We obtain a residue formula for an obstruction to the existence of coupled Kähler-Einstein metrics described by Futaki-Zhang. We apply it to an example studied separately by Futaki…
Coupled Sasaki-Ricci solitons
Akito Futaki, Yingying Zhang
Motivated by the study of coupled Kähler-Einstein metrics by Hultgren and Witt Nyström and coupled Kähler-Ricci solitons by Hultgren, we study in this paper coupled Sasaki-Einstein…
A Liouville-type theorem and Bochner formula for harmonic maps into metric spaces
Brian Freidin, Yingying Zhang
We study analytic properties of harmonic maps from Riemannian polyhedra into CAT() spaces for . Locally, on each top-dimensional face of the domain, this amounts to…
Conflict-free vertex-connections of graphs
Xueliang Li, Yingying Zhang, Xiaoyu Zhu +2
A path in a vertex-colored graph is called \emph{conflict free} if there is a color used on exactly one of its vertices. A vertex-colored graph is said to be \emph{conflict-free ve…
Total proper connection and graph operations
Yingying Zhang, Xiaoyu Zhu
A graph is said to be {\it total-colored} if all the edges and vertices of the graph are colored. A path in a total-colored graph is a {\it total proper path} if any two adja…
