Declaration on digital accessibility

The research training group RTG 2575 Rethinking Quantum Field Theory  makes every effort to make its website barrier-free. The declaration on digital accessibility is required by the law on barrier-free information and communication technology Berlin (BIKTG Bln). The technical requirements for accessibility result from BITV 2.0.

This declaration on digital accessibility applies to the following websites:

When was the accessibility declaration drawn up?

This declaration was last reviewed on 03.11.2020 by Dr. Oliver Bär, coordinator of the RTG 2575.

How barrier-free is the offer?

This website only partially meets the requirements of BITV 2.0.

Which areas are not barrier-free?

We make every effort to make our website barrier-free. We are currently checking the contents of all websites for accessibility and are continuously implementing improvements. Should you notice any content or offers that are not barrier-free, please inform us at

The areas listed below are not or only partially barrier-free for the following reasons:

  • There is no audio description for videos. Due to the disproportionate burden, we do not provide transcription of information-carrying elements (sounds, laughter, applause, etc.), audio description or full-text alternatives for videos
  • We use occasional and temporary font graphics in banners, but usually provide them with alternative texts
  • It may happen that pictures and objects do not contain alt texts, link texts are incomprehensible, abbreviations and foreign language sections are not marked.
  • Contrasts of texts are sometimes not sufficient
