Abstract: This chapter is concerned with a rigorous convergence analysis of a fully discrete Lagrangian scheme for the Hele–Shaw flow, which is the fourth-order thin-film equation with linear mobility in one space dimension. The discretization is based on the equation’s gradient flow structure in the L2-Wasserstein metric. Apart from its Lagrangian character – which guarantees positivity ...
