We would like to encourage you to acknowledge the Action in relevant publications that have benefited from those activities. Such acknowledgements are important for any future assessment of the Action's impact.
Please, acknowledge the Action in publications that
1. benefited from Action activities (online seminars, conferences/workshops, forum interactions and so on);
2. were initiated/inspired during Action activities;
3. involve international collaboration fostered or facilitated by the Action;
4. are outputs of STSMs;
5. are entirely outputs of COST activities (review articles for the WGs, write-up of an invited talk in a COST conference, lecture notes in Action schools, and so on).
For cases 1-3, you can write:
``The authors have benefited from the activities of COST Action CA23115: Relativistic Quantum Information, funded by COST (European Cooperation in Science and Technology)."
possibly with an additional phrase explaining the type of benefit.
For case 4, please acknowledge the STSM as a grant, e.g., you may write:
``This work was supported by an a STSM Grant from COST Action CA23115: Relativistic Quantum Information, funded by COST (European Cooperation in Science and Technology).".
For case 5, please write:
``This work is supported from COST Action CA23115: Relativistic Quantum Information, funded by COST (European Cooperation in Science and Technology).".
Writing the number CA23115 is the most important component of the acknowledgement, as this is the keyword that will be searched.
In some cases, you might want to include the Action as a citation in your document (in papers, research proposals, and so on). I suggest the following
