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.

Massive gravity and Bi-metric gravity as consistent theories of massive spin-2 fields
This talk will describe the recent construction of consistent (ghost free) theories of massive spin-2 fields and their interpretation as theories of massive gravity and bi-metric gravity.
While General Relativity is a theory of a massless spin-2 field, obtaining consistent non-linear theories of massive spin-2 fields has been a long standing problem since the original work of Pauli and Fierz in 1939. In fact, in 1972 and again in 2005, it was argued that such consistent theories may not even exist. This is puzzling since at least massive spin-2 mesons do exist in nature. However, over the past one year, theories of massive spin-2 fields have been constructed and shown to be consistent (ghost free). This has also been extended to theories of interacting massive and massless spin-2 fields. As a straightforward application, such theories can be regarded as theories of modified gravity, that is, massive gravity and bi-metric gravity. The talk will review recent progress in this field.
