Coisotropic Variational Problems
James D. E. Grant, Emilio Musso
In this article we study constrained variational problems in one independent variable defined on the space of integral curves of a Frenet system in a homogeneous space G/H. We prov…

Paraconformal Structures and Integrable Systems
James D. E. Grant
We consider some natural connections which arise between right-flat (p, q) paraconformal structures and integrable systems. We find that such systems may be formulated in Lax form,…

Self-dual two-forms and divergence-free vector fields
James D. E. Grant
Beginning with the self-dual two-forms approach to the Einstein equations, we show how, by choosing basis spinors which are proportional to solutions of the Dirac equation, we may…
