Duality, Matroids, Qubits, Twistors, and Surreal Numbers

摘要

We comment on the possibility that the various concepts such as duality, matroids, qubits, twistors and surreal numbers must be considered as underlying mathematical structures in quantum gravity. Moreover, we argue that extit{via} the Grassmann-Pl"{u}cker relations, these apparent unrelated concepts are, in fact, deeply connected .
