Existence of solutions to numerical schemes using regularization: application to two-phase flow in porous media schemes
Thomas Crozon
The present document corresponds to the 4 th chapter of my thesis, the problem setting is not definitive, what matters most here are the mathematical results and the methodology of…
A note about high-order semi-implicit differentiation: application to a numerical integration scheme with Taylor-based compensated error
Loïc Michel, Jean-Pierre Barbot
In this brief, we discuss the implementation of a third order semi-implicit differentiator as a complement of the recent work by the author that proposes an interconnected semi-imp…
Sparse approximations for contact mechanics
Kiran Sagar Kollepara, José V. Aguado, Yves Le Guennec +2
Low-rank model order reduction strategies for contact mechanics show limited dimensionality reduction due to linear inseparability of contact pressure field. Therefore, a dictionar…
Weighted sparsity and sparse tensor networks for least squares approximation
Philipp Trunschke, Anthony Nouy, Martin Eigel
Approximation of high-dimensional functions is a problem in many scientific fields that is only feasible if advantageous structural properties, such as sparsity in a given basis, c…
