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.

In the talk we consider a variant of the basic problem of the
calculus of variations, where the Lagrangian
is convex and subject to randomness adapted to a Brownian filtration. We
the problem by reducing it, via a limiting argument, to an unconstrained
that consists in finding an absolutely continuous process minimizing the
of the Lagrangian and the deviation of the terminal state from a given
Using the Pontryagin maximum principle one can characterize a solution
of the unconstrained
control problem in terms of a fully coupled forward-backward stochastic
(FBSDE). We use the method of decoupling fields for proving that the
a unique solution.
The talk is based on joint work with Alexander Fromm, Thomas Kruse and
