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.

Stability of the Prandtl System and the Zero Viscosity Limit
The Prandtl system describe the flow of a viscous fluid close to the boundary. It was first derived by Prandtl in 1904. Since, then it had many applications in physics and mathematics. It particular it is a main model in the study of flying objects and the design of airplanes.
The model has a stationary version and a time evolution version. Both of therm are very physical and both of them are mathematically challenging:
A/ The well posedness of the system requires a monotonicity condition or a very high regularity.
B/ The stability of the model is still not well understood: The derivation of the model by studying the zero viscosity limit require a Gevrey regularity.
