Harmonic morphisms and shear-free ray congruences

P. Baird, J. C. Wood

We describe the relationship between complex-valued harmonic morphisms from Minkowski 4-space} and the shear-free ray congruences of mathematical physics. Then we show how a horizo…

Twistorial harmonic morphisms with one-dimensional fibres on self-dual four-manifolds

R. Pantilie, J. C. Wood

We introduce a general notion of twistorial map and classify twistorial harmonic morphisms with one-dimensional fibres from self-dual four-manifolds. Such maps can be characterised…
