Auxiliary Gradient-Flow Solvers for Generalized Newtonian Models
Develops auxiliary gradient-flow solvers that shift nonlinearity in N-function governed variational problems to an auxiliary variable, with metric-space convergence proofs for p-Laplacian and p-Stokes in 4/3 ≤ p ≤ 4 and practical discretizations outperforming Newton in tests.
