Please note that you wrote to the ResearchGate community, not to the RG team. However, the team does not have any capacities to introduce corrections manually. The authors are expected to do this themselves. See "A researcher has wrongly claimed co-authorship of my publication" in https://help.researchgate.net/hc/en-us/articles/14292798510993-Authorship for instructions. But unlike this help page suggests, most probably it was not Karin Ivanova who wrongly claimed authorship, but ResearchGate's automatic algorithm wrongly identified her as co-author and assigned the publication to her profile. Unfortunately, this is a frequent problem in ResearchGate in case of similar names.

sorry and thanks ... and bis sorry
