Twinor Theory: Field Equations from $(A) d S_{4}^{C}$ Spin-Tractors: A Twin to Twistor Theory Modelled on $(A) d S_{4}^{C}$

Chen-Hsu Chien

Twinor theory is formulated as a spacetime-based counterpart to twistor theory using holomorphic reductive Cartan geometry modelled on complexified $(A) d S_{4}$ . The fundamental spin-…

Holomorphic Conformal Cartan Geometry: Conformal Gravity, Twistors, and Ambitwistors

Chen-Hsu Chien

Four-dimensional conformal gravity, twistor theory, and ambitwistor theory are reviewed within the unified framework of holomorphic conformal Cartan geometry. Starting from the spi…
