Space-time waveform relaxation multigrid for Navier-Stokes

James Jackaman, Scott MacLachlan

Space-time finite-element discretizations are well-developed in many areas of science and engineering, but much work remains within the development of specialized solvers for the r…

Predictions Based on Pixel Data: Insights from PDEs and Finite Differences

Elena Celledoni, James Jackaman, Davide Murari +1

As supported by abundant experimental evidence, neural networks are state-of-the-art for many approximation tasks in high-dimensional spaces. Still, there is a lack of a rigorous t…

Constraint-satisfying Krylov solvers for structure-preserving discretisations

James Jackaman, Scott MacLachlan

A key consideration in the development of numerical schemes for time-dependent partial differential equations (PDEs) is the ability to preserve certain properties of the continuum…

Invariant Variational Schemes for Ordinary Differential Equations

Alex Bihlo, James Jackaman, Francis Valiquette

We propose a novel algorithmic method for constructing invariant variational schemes of systems of ordinary differential equations that are the Euler-Lagrange equations of a variat…

Discrete conservation laws for finite element discretisations of multisymplectic PDEs

Elena Celledoni, James Jackaman

In this work we propose a new, arbitrary order space-time finite element discretisation for Hamiltonian PDEs in multisymplectic formulation. We show that the new method which is ob…

On the development of symmetry-preserving finite element schemes for ordinary differential equations

Alex Bihlo, James Jackaman, Francis Valiquette

In this paper we introduce a procedure, based on the method of equivariant moving frames, for formulating continuous Galerkin finite element schemes that preserve the Lie point sym…
