WebSep 5, 2024 · Since the d'Alambertian is the generalization of the Laplacian, I would think that would also describe "harmonic curvature". But apparently harmonic curvature is given by the divergence, not the Laplacian: $$\nabla^iR_{ijkl} = 0$$ Why is this so? And the other thing is, when people describe flow of curvature, instead of the wave equation … WebMar 14, 2024 · Abstract In this article, we will use the harmonic mean curvature flow to prove a new class of Alexandrov-Fenchel type inequalities for strictly convex hypersurfaces in hyperbolic space in terms...

WebApr 12, 2024 · The fluid conductance between two pores i and j is taken to be the harmonic mean of each individual conductance; the conductance g for each phase flow in a tube can be obtained by Poiseuille’s law [24]: (6) g = γ A 2 G μ where A is the cross-section area; and γ a constant related to the cross-section shape (the values for circles ... WebNov 26, 2024 · I know studying the mean curvature flow is a very interesting area of research, I've fooled around with it a bit myself. But it honestly doesn't look like it has much applications within mathematics ...
