Mohammad Wehbe
In this paper we exploit the ideas and formalisms of twistor theory, to show how, on Minkowski space, given a null solution of the wave equation, there are precisely two null direc…

Twistor theory on a finite graph
Paul Baird, Mohammad Wehbe
We show how the description of a shear-free ray congruence in Minkowski space as an evolving family of semi-conformal mappings can naturally be formulated on a finite graph. For th…
