A note on error analysis for a nonconforming discretisation of the tri-Helmholtz equation with singular data
Andreas Bock, Colin Cotter
We apply the nonconforming discretisation of Wu and Xu (2019) to the tri-Helmholtz equation on the plane where the source term is a functional evaluating the test function on a one…

Space-time metamorphosis
Andreas Bock, Colin Cotter
We study the problem of registering images. The framework we use is metamorphosis and we construct a variational Eulerian space-time setting and pose the registration problem as an…
