Someone with same name has claimed authorship of some of my previously published article on research gate? How can I claim my authorship for such articles?
This is a frequent problem in ResearchGate, in most cases caused by an automatic algorithm of RG. See "Another researcher has claimed my publications" in https://explore.researchgate.net/display/support/Authorship for instructions how to correct this. But unlike this help page suggests, most probably it was not the other author himself who wrongly claimed authorship, but ResearchGate's automatic algorithm wrongly identified another researcher as the author and assigned your publication to his profile.
