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 "finite nonassociative algebras obtained from twisted polynomials over chain rings"):
  Abstract: Let S be a unital ring and sigma a ring automorphism of S. We construct unital nonassociative algebras out of the twisted polynomial ring S[t;sigma] and polynomials f(t) in S[t;sigma], whose leading coefficient is a unit. If S is a commutative finite chain ring, these algebras yield examples of generalized Galois rings and can be employed to construct linear codes over commutative finite chain rings.
