Singular Limits of the Shallow Water Equations on the Sphere
Bin Cheng, Steve Schochet
The paper studies how solutions of the slightly compressible shallow water equations on a rapidly rotating sphere behave when the Froude and Rossby numbers become small, proving un…

New Minimal Surfaces of the Sphere and the Hyperbolic Space via Harmonic Morphisms
Sigmundur Gudmundsson, Leonard Nygren Löhndorf
The paper presents a new method using complex-valued harmonic morphisms to construct explicit minimal codimension‑two submanifolds in the 4‑sphere and 4‑dimensional hyperbolic spac…
