Unexpected Analytic Phenomena on Finsler Manifolds
Benling Li, Wei Zhao
In the Riemannian setting, every flat Cartan--Hadamard manifold is isometric to Euclidean space, the canonical model that underlies the theory of Sobolev spaces and guarantees the…

Hilbert's fourth problem in the constant curvature setting
Benling Li, Wei Zhao
Hilbert's fourth problem seeks the classification of metric geometries where straight lines are shortest paths. Its regular case identifies the projectively flat Finsler manifolds.…

Structure of Massive Gauge/Gravity Scattering Amplitudes, Equivalence Theorems, and Extended Double-Copy with Compactified Warped Space
Yanfeng Hang, Wei-Wei Zhao, Hong-Jian He +1
We study the structure of scattering amplitudes of massive Kaluza-Klein (KK) states in the compactified 5-dimensional warped gauge and gravity theories. We present systematic formu…
