SUMMARY:Dennis The\, On 4D Split-conformal Structures with G2-symmetric Twistor Distribution
DESCRIPTION:    Speaker\n\n\nDennis The\nThe Artic University of Norway\, Tromso\n\n\n\n\n\n\nIn their 2013 article\, An & Nurowski considered two surfaces rolling on each other without twisting or slipping\, and defined a twistor distribution (on the space of all real totally null self-dual 2-planes) for the associated 4D split-signature conformal structure. If this split-conformal structure is not anti-self dual\, then the twistor distribution is a (2\,3\,5)-distribution\, and An-Nurowski identified interesting rolling examples where it achieves maximal\, i.e. G2\, symmetry. Relaxing the rolling assumption\, a similar construction can be made for any 4D split-conformal structure\, and my talk will discuss a broader classification of examples where such exceptional symmetry for the twistor distribution is achieved. (Joint work with Pawel Nurowski & Katja Sagerschnig.)
