Twistor surfaces and right-flat spaces
General Relativity and Gravitation, 1978 The connection between the deformed twistor space of Penrose and Plebanski's form for the general right-flat metric is explored. A Hamiltonian formalism for obtaining the twistor surfaces in a right-flat space with Plebanski's Ω-function as Hamiltonian is obtained.

Twistor Space for Rolling Bodies [PDF]
Communications in Mathematical Physics, 2013 On a natural circle bundle T(M) over a 4-dimensional manifold M equipped with a split signature metric g, whose fibers are real totally null selfdual 2-planes, we consider a tautological rank 2 distribution D obtained by lifting each totally null plane horizontally to its point in the fiber.

Kinematic Lie Algebras from Twistor Spaces
Physical Review Letters, 2023 We analyze theories with color-kinematics duality from an algebraic perspective and find that any such theory has an underlying BV${}^{\color{gray} \blacksquare}$-algebra structure, extending the ideas of arXiv:1912.03110. Conversely, we show that any theory with a BV${}^{\color{gray} \blacksquare}$-algebra features a kinematic Lie algebra that ...

Proceedings of the London Mathematical Society, 1981 The work of R. Penrose has shown the deep relationship between the conformal structure of Minkowski space and the complex geometry of lines in projective three-space. This transformation applies to a more general class of conformal structures and in particular there is a riemannian version, described in [5], which is itself of interest to mathematical ...

Degenerations of LeBrun Twistor Spaces [PDF]
Communications in Mathematical Physics, 2010 We investigate various limits of the twistor spaces associated to the self-dual metrics on n CP ^2, the connected sum of the complex projective planes, constructed by C. LeBrun. In particular, we explicitly present the following 3 kinds of degenerations whose limits of the metrics are: (a) LeBrun metrics on (n-1) CP ^2$, (b) (Another) LeBrun metrics on
