Abstract robust coarse spaces for systems of PDEs via generalized eigenproblems in the overlaps [PDF]
Coarse spaces are instrumental in obtaining scalability for domain decomposition methods for partial differential equations (PDEs). However, it is known that most popular choices of coarse spaces perform rather weakly in the presence of heterogeneities ...

Epistemic Norms, A Priority, and Self-Knowledge [PDF]
This thesis is primarily focussed on developing a novel characterisation of the distinction between a priori and a posteriori justification. My working hypothesis is that we can make a surprising amount of progress in this field by paying attention to ...

Stochastic PDEs with multiscale structure [PDF]
We study the spatial homogenisation of parabolic linear stochastic PDEs exhibiting a two-scale structure both at the level of the linear operator and at the level of the Gaussian driving noise.

Analysis of an energy-based atomistic/continuum approximation of a vacancy in the 2D triangular lattice [PDF]
We present an a priori error analysis of a practical energy based atomistic/continuum coupling method (A. V. Shapeev, Multiscale Model. Simul., 9(3):905-932, 2011) in two dimensions, for finite-range pair-potential interactions, in the presence of ...

Robust a priori and a posteriori error analysis for the approximation of Allen–Cahn and Ginzburg–Landau equations past topological changes [PDF]
A priori and a posteriori error estimates are derived for the numerical approximation of scalar and complex valued phase field models. Particular attention is devoted to the dependence of the estimates on a small parameter and to the validity of the ...

A priori and a posteriori analysis of the quasinonlocal quasicontinuum method in 1D [PDF]
For a next-nearest neighbour pair interaction model in a periodic domain, a priori and a posteriori analyses of the quasinonlocal quasicontinuum method (QNL-QC) are presented.

A priori estimates for rough PDEs with application to rough conservation laws [PDF]
International audienceWe introduce a general framework to study PDEs driven by rough paths: we develop new a priori estimates based on a rough Gronwall lemma argument for weak solutions to rough PDEs.

A priori error estimates for energy-based quasicontinuum approximations of a periodic chain [PDF]
We derive a priori error estimates for three prototypical energy-based quasicontinuum (QC) methods: the local QC method, the energy-based QC method, and the quasi-nonlocal QC method.

A priori estimates for quasilinear parabolic systems with quadratic nonlinearities in the gradient [PDF]
summary:We derive local a priori estimates of the Hölder norm of solutions to quasilinear elliptic systems with quadratic nonlinearities in the gradient.
