The "Timelike boundaries in Theories of Gravity" workshop aims to bring together a select group of experts in the topic of timelike boundaries in gravity. Recently, this has gathered the attention of different communities in theoretical physics, including:

• Mathemtical relativity,
• Numerical relativity,
• Gravitational Holography and,
• Quantum Gravity.

The one-week event will provide a platform for in-depth discussions and collaboration among participants.

_Location_
The meeting will take place in the beautiful UNESCO’s world heritage city of Morelia, Mexico, hosted by the Universidad Michoacana de San Nicolás de Hidalgo.

_Direction_

Lectures will take place in the Centro Cultural Universitario , a historial building in the city centre of Morelia.

_Where to Stay_

We expect to be able to cover accommodation for most workshop participants. Confirmed participants will be contacted for suitable arrangements.

_Schedule_

The main idea of the workshop is to connect different researchers interested in the problem of timelike boundaries in gravity from different perspectives. As such, we are planning for a highly-interactive workshop, with lots of time for discussion and informal interactions between the participants. Each day there will be a set of formal talks covering the different topics.

We expect to discuss the following topics: Foundations of gravity with boundaries, edge effects in gravity, quantum gravity in finite regions of spacetime, holography with finite timelike boundaries, and numerical relativity with timelike boundaries.

_Talk titles_
_Monday_
Anderson: Finite boundaries in classical gravity.
Lau: Regularization of gauge-preserving boundary conditions for the helically reduced Einstein equations.
_Tuesday_
Vukasinac: Canonical vs. covariant: First order gravity in regions with boundaries.

_Public Talk_

As part of the workshop, we are organising a public talk to be held at the Centro Universitario and aimed at to the general public of Morelia. Details to come soon (but expect the public talk to be in Spanish).

Date and time: Friday August 9th at 7pm.

This workshop is possible due to the generous contribution of the Gravity Theory Trust. At this time, the event is by invitation only. If you want to participate, please contact us.
