3D Einstein action from 6D Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +1
In view of embedding 3D gravity into topological string theory, we show that the dimensional reduction of 6D Kodaira-Spencer gravity on , i.e. the low-energ…

Complexity and the Hilbert space dimension of 3D gravity
Vijay Balasubramanian, Rathindra Nath Das, Johanna Erdmenger +2
A central problem in formulating a theory of quantum gravity is to determine the size and structure of the Hilbert space of black holes. Here we use a quantum dynamical Krylov comp…

Topological Einstein gravity as Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +3
As a contribution towards quantizing three-dimensional gravity, we show at the classical level that Euclidean three-dimensional Einstein gravity with a negative cosmological consta…
