In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

The aim of this TH-institute will be to discuss recent developments in theoretical aspects of black holes, in particular on understanding the fate of the classical horizon at the quantum level.
In classical General Relativity, black holes are the generic endpoint of gravitational collapse. They are characterized by an event horizon separating two causally disconnected regions, one visible to an asymptotic observer, the other accessible to an infalling observer. Semi-classical reasoning suggests that black holes decay by Hawking emission and eventually disappear. This is in potential conflict with the basic postulates of quantum mechanics, which require that information carried by the collapsing matter must be conserved. This paradox has catalyzed most of the recent progress in understanding the nature of quantum gravity, but has eluded a fully satisfactory solution so far. Recent thoughts experiments suggest that the semi-classical picture of a smooth, eventless horizon may be invalid, at least for old black holes which have radiated most of their entropy. The alternative to this semi-classical picture has been widely discussed over the last year, with no definite answer yet. The workshop will focus on the implications of these thought experiments for the fundamental nature of gravity, and related issues.
The workshop will bring together leading quantum gravity experts to discuss these issues, with a light schedule of seminars leaving plenty of time for informal discussions.
