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 "construction a of lattices over number fields and block fading wiretap coding"):
  Abstract: We propose a lattice construction from totally real and complex multiplication fields, which naturally generalizes Construction A of lattices from    $p$   -ary codes obtained from the cyclotomic field    $ \mathbb {Q}(\zeta _{p})$   ,    $p$    a prime, which in turn contains the so-called Construction A of lattices from binary codes as a particular case. We focus on the maximal totally real subfield    $ \mathbb {Q}(\zeta _{p^{r}}\,+\,\zeta _{p}^{-r})$    of the cyclotomic field    $ \mathbb {Q}(\zeta _{p^{r}})$   ,    $r\geq 1$   . Our construction has applications to coset encoding of algebraic lattice codes for block fading channels, and in particular for block fading wiretap channels.
