When I add my publications onto my profile, it says: "This DOI is already associated with a different research item on ResearchGate. If the research item is yours, please confirm your authorship to add it to your profile. To continue editing the details of this research item, simply delete the DOI you entered."

But if I ignore adding DOI, I will get "You can not claim this publication."

This is because somebody wrongly added my publications onto her profile. In this case, what can I do if I connected her without response?

Thanks!
