The infinity Laplacian, a highly degenerate elliptic operator formally defined by Δ∞u = uₓᵢ uₓⱼ uₓᵢₓⱼ, has emerged as a central object in the study of L∞ variational problems and optimal Lipschitz ...

In the past few decades, the use of phase field-modeling equations for mathematical modeling has progressed. Phase separation has been studied extensively in thermodynamics and materials engineering, ...

Graph curvature and Laplacian operators form a vibrant area of research at the intersection of differential geometry and graph theory. The concept of graph curvature, inspired by classical Ricci ...
