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 "quantitative aspects of linear and affine closed lambda terms"):
  Abstract: Affine $$\lambda$$-terms are $$\lambda$$-terms in which each bound variable occurs at most once and linear $$\lambda$$-terms are $$\lambda$$-terms in which each bound variables occurs once. and only once. In this paper we count the number of closed affine $$\lambda$$-terms of size $n$, closed linear $$\lambda$$-terms of size $n$, affine $$\beta$$-normal forms of size $n$ and linear $$\beta$$-normal forms of ise $n$, for different ways of measuring the size of $$\lambda$$-terms. From these formulas, we show how we can derive programs for generating all the terms of size $n$ for each class. For this we use a specific data structure, which are contexts taking into account all the holes at levels of abstractions.
