Positive curvature, like that on a sphere, implies a finite universe, while zero curvature, as on a flat plane or negative ...

Inspired by the cells in leaves that control leaf curvature to regulate water loss, researchers present flat panels that can morph into a stiff, complex 3D structure with a different Gaussian ...

We prove some versions of the Schwarz lemma for real harmonic functions in certain Riemann surfaces with positive Gauss curvature. Journal Information Rocky Mountain Journal of Mathematics publishes ...

In a recently published article in the journal Physics Letters B, researchers investigated the propagation of light within a theoretical model known as an elliptic wormhole (EWH), characterized by ...

Cells can sense and respond to surface curvature in very clever ways, as shown in research. The results, which revealed that curvature is a profound biological cue, could pave the way to new tools in ...
