In this article, we introduce and analyze a general procedure for approximating a ‘black and
white’ shape and topology optimization problem with a density optimization problem, …

We study dispersive effects of wave propagation in periodic media, which can be modelled
by adding a fourth-order term in the homogenized equation. The corresponding fourth-order …

We study a finite element computational model for solving the coupled problem arising in
the interaction between a free fluid and a fluid in a poroelastic medium. The free fluid is …

We provide both a general framework for discretizing de Rham sequences of differential
forms of high regularity, and some examples of finite element spaces that fit in the framework. …

In this paper we consider large scale nonlinear least-squares problems for which function
and gradient are evaluated with dynamic accuracy and propose a Levenberg–Marquardt …

We use the H-matrix technology to compute the approximate square root of a covariance
matrix in linear cost. This allows us to generate normal and log-normal random fields on …

We introduce a new family of strong linearizations of matrix polynomials—which we call “block
Kronecker pencils”—and perform a backward stability analysis of complete polynomial …
