Keywords: Polynomial weights, multiple authorship, credit assignment. 1 Introduction Assigning weights to multiple authors of a paper is a challenging task. Thechallenge comes from the fact that the conventions followed among diﬀerentareas of research are diﬀerent, and there is no universally agreed upon policyfor sharing credits of a multiauthored paper. The reason is that the conventionsfollowed among research groups might not depend only on the academic factors,sometimes, these conventionmight alsodepend onthe social, economic, regional,and scientiﬁc factors. Actually, a weight assignment scheme can only generateweights. How judiciously the scheme is applied is the responsibility of the onewho is evaluating the quality of research produced by an author or a set ofauthors. How the weights generated by a weight assignment policy can bemade in the conformance of the conventions followed by a research group ispartly described in [3]. We here focus on the schemes that generate weights(and not that are applied to a particular research ﬁeld).Many researchers focused on weight assignment schemes for sharing creditsamong multiple authors of a paper. Addressing multiple authorship mathemat-ically dates back to [4]. In [2], a weight assignment scheme called
