Equal Weights Coauthorship Sharing and Shapley Value are Equivalen

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
