50. Asymptotically safe quantum gravity on foliated spacetimes

Frank Saueressig

invited talk

The gravitational asymptotic safety program is a promising candidate for a quantum theory of the gravitational interactions. Traditionally, many investigations have been carried out in an Euclidean setting and the transition to Lorentzian signature computations has started only recently. In this talk, I will give a pedagogical introduction to the key elements of asymptotic safety before...

60. Asymptotically safe - canonical quantum gravity junction

invited talk

We show in a concrete model that asymptotically safe and canonical quantum gravity
methods can be brought into harmonic interaction despite the fact that the two
formulations employ different metric signatures. Focus is laid on concepts rather
than technical details to make this contribution hopefully useful for researchers of both communities.

53. The universal swampland

Astrid Eichhorn

invited talk

The swampland is the space of those effective field theories that cannot be ultraviolet completed in quantum gravity. Understanding the swampland is relevant for phenomenological model-building and for observational tests of quantum gravity.
This talk will have three parts:
First, I will introduce the notion relative swamplands, to distinguish the swamplands of different quantum-gravity...
