Twistors, CFT and Holography | | Kirill Krasnov
; | | Date: |
18 Nov 2003 | | Subject: | hep-th | | Affiliation: | AEI, Golm/Potsdam | | Abstract: | According to one of many equivalent definitions of twistors a (null) twistor is a null geodesic in Minkowski spacetime. Null geodesics can intersect at points (events). The idea of Penrose was to think of a spacetime point as a derived concept: points are obtained by considering the incidence of twistors. One needs two twistors to obtain a point. Twistor is thus a ``square root’’ of a point. In the present paper we entertain the idea of quantizing the space of twistors. Twistors, and thus also spacetime points become operators acting in a certain Hilbert space. The algebra of functions on spacetime becomes an operator algebra. We are therefore led to the realm of non-commutative geometry. This non-commutative geometry turns out to be related to conformal field theory and holography. Our construction sheds an interesting new light on bulk/boundary dualities. | | Source: | arXiv, hep-th/0311162 | | Services: | Forum | Review | PDF | Favorites | |
