human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Towards verifying VHDL descriptions of processors"):
  Abstract: We present a system for the formal verification of processors which combines a computer algebra simplification tool with an object-oriented approach. It has been successfully used for verifying the DP32 processor described in the VHDL Cookbook. A general VHDL description style for proving processors is derived from this case study.

Includes members:
  Member "An Object-Oriented Framework for the Formal Verification of Processors":
    also connected through other hyperedges:
      (none)

Question: Please tell me which research area the co-authored paper (i.e., the source paper of the center hyperedge) belongs to. The 4 classes are: Computer science, Mathematics, Engineering, Economics, Psychology, Business. Directly output the class name.
