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 "a dependent nominal type theory"):
  Abstract: Nominal abstract syntax is an approach to representing names and binding#N#pioneered by Gabbay and Pitts. So far nominal techniques have mostly been#N#studied using classical logic or model theory, not type theory. Nominal#N#extensions to simple, dependent and ML-like polymorphic languages have been#N#studied, but decidability and normalization results have only been established#N#for simple nominal type theories. We present a LF-style dependent type theory#N#extended with name-abstraction types, prove soundness and decidability of#N#beta-eta-equivalence checking, discuss adequacy and canonical forms via an#N#example, and discuss extensions such as dependently-typed recursion and#N#induction principles.
