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.

Random periodicity is ubiquitous in the real world. In this talk, I will provide the concepts of random periodic paths and periodic measure to mathematically describe random periodicity. These two different notions are “equivalent”. An ergodic theory is established. For Markovian random dynamical systems, in the random periodic case, the infinitesimal generator of the Markovian has infinite number of equally placed simple eigenvalues including 0 on the imaginary axis, in contrast to the mixing stationary case in which the Koopman-von Neumann Theorem says there is only one simple eigenvalue 0 on the imaginary axis. Examples of of Markov chains, random mappings, stochastic differential equations and stochastic partial differential equations with random periodic paths or periodic measures will be provided. This theory implies law of large numbers, central limit theorems and applications to time series (touched if time permits).
