27 Jul 1992 | | Journal: | Phys.Rev. D47 (1993) 3496-3508 | | Subject: | hep-th | | Abstract: | It is shown that self-dual theories generalize to four dimensions both the conformal and analytic aspects of two-dimensional conformal field theories. In the harmonic space language there appear several ways to extend complex analyticity (natural in two dimensions) to quaternionic analyticity (natural in four dimensions). To be analytic, conformal transformations should be realized on $CP^3$, which appears as the coset of the complexified conformal group modulo its maximal parabolic subgroup. In this language one visualizes the twistor correspondence of Penrose and Ward and consistently formulates the analyticity of Fueter. | | Source: | arXiv, hep-th/9207089 | | Services: | Forum | Review | PDF | Favorites | |
