Two key ideas have greatly improved techniques for image enhancement and denoising: the lifting of image data to multi-orientation distributions and the application of nonlinear …
We analyse the functional 𝒥 (u)=∥∇ u∥∞ defined on Lipschitz functions with homogeneous Dirichlet boundary conditions. Our analysis is performed directly on the …
The p-Laplacian is a non-linear generalization of the Laplace operator. In the graph context, its eigenfunctions are used for data clustering, spectral graph theory, dimensionality …
Extracting the latent underlying structures of complex nonlinear local and nonlocal flows is essential for their analysis and modeling. In this Element the authors attempt to provide a …
Assignment flows are smooth dynamical systems for data labeling on graphs. Although they exhibit structural similarities with the well-studied class of replicator dynamics, it is nontrivial …

We address the problem of computing the graph $ p $-Laplacian eigenpairs for $ p\in (2,\infty) $. We propose a reformulation of the graph $ p $-Laplacian eigenvalue problem in …
Neural networks have revolutionized the field of data science, yielding remarkable solutions in a data-driven manner. For instance, in the field of mathematical imaging, they have …
In this work, we present an alternative formulation of the higher eigenvalue problem associated to the infinity Laplacian, which opens the door for numerical approximation of …
