Battiston et al. (arXiv:2110.06023) provide a comprehensive overview of how investigations complex systems should take into account interactions between more than two elements, which can be modelled by hypergraphs and studied via topological data analysis. Following separate line enquiry, broad literature has developed information-theoretic tools to characterize high-order interdependencies fro...

The multislope concept has been recently introduced in the literature to deal with MUSCL reconstructions on triangular and tetrahedral unstructured meshes in the finite volume cell-centered context. Dedicated scalar slopes are used to compute the interpolations on each face of a given element, in opposition to the monoslope methods in which a unique limited gradient is used. The multislope appr...
