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.

Exploring new frontiers in strong-field gravity with gravitational waves1h
The recent detections of gravitational waves from merging black holes and neutron stars have established gravitational waves as a new cosmological messenger and opened unique opportunities for probing gravity and matter in unexplored regimes. I will discuss the basic physics of gravitational waves, the facilities and methods for detecting and interpreting the signals, and the remarkable insights we have gained from the observations to date. I will conclude with an outlook onto the exciting prospects and challenges for the next years as the field of gravitational wave physics moves from the discovery era to one of precision physics.

συµπλεκτικoς and Complexus when two complexities (almost) meet1h
(joint work with Michel Cahen)
Symplectic geometry has its origins in the Hamiltonian formulation of classical mechanics. Complex geometry is on the crossroad of algebraic and differential geometry. In differential geometry it yields the notion of almost complex structures.
Kähler geometry is at the intersection of symplectic and complex geometry.
I shall recall examples and properties of those three geometries and examples of symplectic manifolds which are not Kähler.
All symplectic manifolds admit almost complex structures.
I shall exhibit geometrical structures associated to (non complex) almost complex structures on a symplectic manifold.
