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.

Double Poisson and double quasi-Poisson algebras were introduced by M. Van den Bergh in his study of noncommutative quasi-Poisson geometry. Namely, they satisfy the so-called Kontsevich-Rosenberg principle, since the representation scheme of a double (quasi-)Poisson algebras has a natural (quasi-)Poisson structure. On the other hand, N. Iyudu and M. Kontsevich found a link between double Poisson algebras and pre-Calabi-Yau algebras, a notion introduced by Kontsevich and Y. Vlassopoulos.The aim of this talk will be to explain how such connection can be extended to double quasi-Poisson algebras, which thus give rise to pre-Calabi-Yau algebras. This pre-Calabi-Yau structure is however more involved in the case of double quasi-Poisson algebras since, in particular, we get an infinite number of nonvanishing higher multiplications for the associated pre-Calabi-Yau algebra, which involve the Bernoulli numbers.
