Query: Four-dimensional Quantum Gravity with a Cosmological Constant from
  Three-dimensional Holomorphic Blocks   Prominent approaches to quantum gravity struggle when it comes to
incorporating a positive cosmological constant in their models. Using
quantization of a complex $\mathrm{SL}(2,\mathbb{C})$ Chern-Simons theory we
include a cosmological constant, of either sign, into a model of quantum
gravity.
