The connected prescription for form factors in twistor space [PDF]
, 2016 A bstractWe propose a connected prescription formula in twistor space for all tree-level form factors of the stress tensor multiplet operator in N$$ \mathcal{N} $$ = 4 super Yang-Mills, which is a generalisation of the expression of Roiban, Spradlin and ...

Gravity from rational curves in twistor space. [PDF]
Physical Review Letters, 2012 This Letter presents a new formula which is conjectured to yield all tree amplitudes in N=8 supergravity. The amplitudes are described in terms of higher degree rational maps to twistor space.

The momentum amplituhedron of SYM and ABJM from twistor-string maps
Journal of High Energy Physics, 2022 We study remarkable connections between twistor-string formulas for tree amplitudes in N $$ \mathcal{N} $$ = 4 SYM and N $$ \mathcal{N} $$ = 6 ABJM, and the corresponding momentum amplituhedron in the kinematic space of D = 4 and D = 3, respectively ...

Complex Multiplication in Twistor Spaces [PDF]
International Mathematics Research Notices, 2020 AbstractDespite the transcendental nature of the twistor construction, the algebraic fibres of the twistor space of a K3 surface share certain arithmetic properties. We prove that for a polarised K3 surface with complex multiplication, all algebraic fibres of its twistor space away from the equator have complex multiplication as well.

Instantons on the six-sphere and twistors [PDF]
, 2012 We consider the six-sphere S^6=G_2/SU(3) and its twistor space Z=G_2/U(2) associated with the SU(3)-structure on S^6. It is shown that a Hermitian Yang-Mills connection (instanton) on a smooth vector bundle over S^6 is equivalent to a flat partial ...

International Journal of Mathematics and Mathematical Sciences, 1986 We describe briefly the basic ideas and results of the twistor theory. The main points: twistor representation of Minkowsky space, Penrose correspondence and its geometrical properties, twistor interpretation of linear massless fields, Yang-Mills fields (

Twistor spaces for Riemannian symmetric spaces [PDF]
Mathematische Annalen, 1993 We determine the structure of the zero-set of the Nijenhuis tensor of the natural almost complex structure \(J_ 1\) on the total space of the bundle \(J(G/K,g)\) of Hermitian structures on the tangent spaces of any even-dimensional Riemannian symmetric space \(G/K\) of compact or non- compact type.

Twistor Interpretation of Harmonic Spheres and Yang–Mills Fields
Mathematics, 2015 We consider the twistor descriptions of harmonic maps of the Riemann sphere into Kähler manifolds and Yang–Mills fields on four-dimensional Euclidean space.
