A mixed finite element method for nonlinear diffusion equations

TL;DR: In this paper, a mixed finite element method was proposed for a class of nonlinear diffusion equations, which is based on their interpretation as gradient flows in optimal transportation metrics, leading to a mixed symmetric formulation.

Fast Diffusion to Self-Similarity: Complete Spectrum, Long-Time Asymptotics, and Numerology

TL;DR: In this article, the spectrum of Open image in new window on the Sobolev space W 1,2ρ(Rn) formed by closing the smooth functions of compact support with respect to the norm is determined.

Weak SINDy for partial differential equations

TL;DR: The Weak SINDy framework is extended to the setting of partial differential equations (PDEs), and the elimination of pointwise derivative approximations via the weak form enables effective machine-precision recovery of model coefficients from noise-free data and robust identification of PDEs in the large noise regime.

Climb-enabled discrete dislocation plasticity

TL;DR: In this paper, a small strain two-dimensional discrete dislocation plasticity framework coupled to vacancy diffusion is developed wherein the motion of edge dislocations is by a combination of glide and climb.
