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.

After short historical introduction about the description of fundamental interactions I shall recall the nonrenormalizability of quantum gravity (QG) in perturbative QFT approach. It will be pointed out the difference between the notion of space-time fields in particle physics and in quantum gravity taking into consideration the dynamical nature of space-time. In particular it will be pointed out the appearance of noncommutative space-times as characteristic feature of QG at Planck distances. Further we shall consider briefly four main approaches to QG:
a) Loop quantum gravity,
b) QG as deformed field theory on noncommutative space-time,
c) Functional formulation of QG and lattice approach,
d) QG as a sector of quantized string field theory.
We argue that these approaches are rather complementary in formulating
of QG model with desired properties (covariance under local diffeomorphisms, background space- time field independence, appearance of noncommutative space-times at ultrashort distances, finiteness of calculated QG effects, incorporation of QG into unified model of fundamental interactions).
