Celestial w1+∞ Symmetries from Twistor Space [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2021 . We explain how twistor theory represents the self-dual sector of four dimensional gravity in terms of the loop group of Poisson diffeomorphisms of the plane via Penrose’s nonlinear graviton construction.

Twistor Theory of the Airy Equation [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2014 We demonstrate how the complex integral formula for the Airy functions arises from Penrose's twistor contour integral formula. We then use the Lax formulation of the isomonodromy problem with one irregular singularity of order four to show that the Airy equation arises from the anti-self-duality equations for conformal structures of neutral signature ...

Twistor coverings and Feynman diagrams
Journal of High Energy Physics, 2022 Recently, a worldsheet dual to free N $$ \mathcal{N} $$ = 4 Super Yang-Mills has been proposed in terms of twistor variables for AdS5, in parallel to that for the AdS3 dual to the free symmetric orbifold CFT. In the latter case, holomorphic covering maps

A twistorial description of the IKKT-matrix model
Journal of High Energy Physics, 2022 We consider the fuzzy 4-sphere S N 4 $$ {S}_N^4 $$ as a background in the IKKT matrix model, and explore the relation between S N 4 $$ {S}_N^4 $$ and fuzzy twistor space in the semi-classical limit.

Twistors, the ASD Yang-Mills equations and 4d Chern-Simons theory
Journal of High Energy Physics, 2023 We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills equations are closely related, at least classically.

Conformal higher spin theory and twistor space actions [PDF]
, 2016 We consider the twistor description of conformal higher spin theories and give twistor space actions for the self-dual sector of theories with spin greater than two that produce the correct flat space-time spectrum.

A Deformation of Twistor Space and a Chiral Mass Term in N=4 Super Yang-Mills Theory [PDF]
, 2005 Super twistor space admits a certain (super) complex structure deformation that preserves the Poincare subgroup of the symmetry group PSL(4|4) and depends on 10 parameters.

Mini-twistors and the Cotton double copy
Journal of High Energy Physics, 2023 The double copy relates quantities in gauge, gravity and related theories. A well-known procedure for relating exact classical solutions is the Weyl double copy in four spacetime dimensions, and a three-dimensional analogue of this — the Cotton double ...
