Moduli Space of Topological 2-form Gravity
We propose a topological version of four-dimensional (Euclidean) Einstein gravity, in which anti-self-dual 2-forms and an SU(2) connection are used as fundamental fields. The theory describes the moduli space of conformally self-dual Einstein manifolds. In the presence of a cosmological constant, we evaluate the index of the elliptic complex associated with the moduli space. e-mail: [email protected]...
متن کاملGravitational instantons and moduli spaces in topological two-form gravity.
A topological version of four-dimensional (Euclidean) Einstein gravity which we propose regards anti-self-dual 2-forms and an anti-self-dual part of the frame connections as fundamental fields. The theory describes the moduli spaces of conformally self-dual Einstein manifolds for a cosmological constant Λ 6= 0 case and Einstein-Kählerian manifold with the vanishing real first Chern class for Λ ...
متن کاملQuantized Topological 2-form Gravity
We develop a perturbation theory of four-dimensional topological 2form gravity without cosmological constant. A 2-form and an SU(2) connection 1-form are used as fundamental variables instead of metric. There is no quantum correction from two-loop and higher orders in covariant gauge, in Landau gauge and in background covariant gauge. We improve naive dimensional regularization and calculate an...
متن کاملModuli Spaces in the Four-Dimensional Topological Half-Flat Gravity
We classify the moduli spaces of the four-dimensional topological half-flat gravity models by using the canonical bundle. For a K3-surface or T 4 , they describe an equivalent class of a trio of the Einstein-Kähler forms (the hyperkähler forms). We calculate the dimensions of these moduli spaces by using the Atiyah-Singer Index theorem. We mention the partition function and the possibility of t...
متن کاملTopological M-theory as Unification of Form Theories of Gravity
We introduce a notion of topological M-theory and argue that it provides a unification of form theories of gravity in various dimensions. Its classical solutions involve G2 holonomy metrics on 7-manifolds, obtained from a topological action for a 3-form gauge field introduced by Hitchin. We show that by reductions of this 7-dimensional theory one can classically obtain 6-dimensional topological...
