Valuative invariants with higher moments
Kewei Zhang
In this article we introduce a family of valuative invariants defined in terms of the -th moment of the expected vanishing order. These invariants lie between and -invari…
Angle deformation of Kähler-Einstein edge metrics on Hirzebruch surfaces
Yanir A. Rubinstein, Kewei Zhang
We construct a family of Kähler-Einstein edge metrics on all Hirzebruch surfaces using the Calabi ansatz and study their angle deformation. This allows us to verify in some special…
Compensated Convex Based Transforms for Image Processing and Shape Interrogation
Antonio Orlando, Elaine Crooks, Kewei Zhang
This paper reviews some recent applications of the theory of the compensated convex transforms or of the proximity hull as developed by the authors to image processing and shape in…
On the optimal volume upper bound for Kähler manifolds with positive Ricci curvature (with an appendix by Yuchen Liu)
Kewei Zhang
Using -invariants and Newton--Okounkov bodies, we derive the optimal volume upper bound for Kähler manifolds with positive Ricci curvature, from which we get a new characterizat…
On the Cheltsov--Rubinstein conjecture
Kento Fujita, Yuchen Liu, Hendrik Süß +2
In this note we investigate the Cheltsov--Rubinstein conjecture. We show that this conjecture does not hold in general and some counterexamples will be presented.
Compensated Convexity on Bounded Domains, Mixed Moreau Envelopes and Computational Methods
Kewei Zhang, Antonio Orlando, Elaine Crooks
Compensated convex transforms have been introduced for extended real-valued functions defined over . In their application to image processing, interpolation, and shap…
