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.

We describe the statistical mechanics of a melting crystal in three dimensions, and its relationships with diverse topics in mathematical physics. On the mathematics side, the model is connected to the combinatorics of plane partitions and the enumeration of Donaldson-Thomas invariants in algebraic geometry. On the physics side, it is related to certain integrable hierarchies, matrix models, Chern-Simons gauge theory, and a toy model of quantum gravity in six dimensions. Its partition function can also be computed by enumerating the contributions from noncommutative instantons to a six-dimensional topological gauge theory; this yields an interpretation of the melting crystal model as a discretization of six-dimensional spacetime at the Planck scale. We also describe analogous relations between a melting crystal model in two dimensions and N=4 supersymmetric Yang-Mills theory in four dimensions.
