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, ...
