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 کاملA Topological Model for Two-dimensional Gravity Coupled to Matter
Starting from a topological gauge theory in two dimensions with symmetry groups ISO(2, 1), SO(2, 1) and SO(1, 2) we construct a model for gravity with non-trivial coupling to matter. We discuss the equations of motion which are connected to those of previous related models but incorporate matter content. We also discuss the resulting quantum theory and finally present explicit formulæ for topol...
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 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 کاملOn Topological 2D String and Intersection Theory
The topological description of 2D string theory at the self-dual radius is studied in the algebro-geometrical formulation of the Ak+1 topological models at k = −3. Genus zero correlators of tachyons and their gravitational descendants are computed as intersection numbers on moduli space and compared to 2D string results. The interpretation of negative momentum tachyons as gravitational descenda...
