human: Given a node-centered hypergraph: <hypergraph>, where nodes represent authors and hyperedges represent groups of authors who co-authored the same paper.

Details of the hypergraph:
Center node: "The influence of merging on h-type indices"
  Abstract: Each information production process has a unique h-index. This paper studies the problem: what are possible h-index values if we merge two or more IPPs?

Connected through hyperedge HE-1 (induced by source paper "h-Index: A review focused in its variants, computation and standardization for different scientific fields"):
  with members:
    - "A Fuzzy Method for the Assessment of the Scientific Production"
    - "A quantile approach to integration with respect to non-additive measures"

Question: Please tell me which research area the center author belongs to. The 4 classes are: Computer science, Mathematics, Engineering, Economics, Psychology, Business. Directly output the class name.

gpt: Computer science
