Equal Weights Coauthorship Sharing and Shapley Value are Equivalent

The publication credit allocation problem  is one of the  fundamental problems  in bibliometrics. The solution of this problem provides the basis of further research.  There are two  solutions which do  not require any additional information: equal weights measure and Shapley value. Until recently Shapley value is not used because of hardness of computing. The paper  justifies the equal weights measure by showing equivalence with the Shapley value approach for sharing coauthors performance in specific games.
