Euclidean wormholes in Hořava-Lifshitz gravity

Euclidean wormholes first appeared in the Euclidean path integral approach to quantum gravity. In a more general way, Hawking and Page interpreted such configurations as solutions to the Wheeler-DeWitt equation with appropriate boundary conditions. We study Euclidean wormholes in the framework of the Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz theory of gravity. We use its projectable version to obtain the Wheeler-DeWitt equation of a...
