human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "typing weak msol properties"):
  Abstract: We consider lambda-Y-calculus as a non-interpreted functional programming language: the result of the execution of a program is its normal form that can be seen as the tree of calls to built-in operations. Weak monadic second-order logic (wMSOL) is well suited to express properties of such trees. We give a type system for ensuring that the result of the execution of a lambda-Y-program satisfies a given wMSOL property. In order to prove soundness and completeness of the system we construct a denotational semantics of lambda-Y-calculus that is capable of computing properties expressed in wMSOL.
