“…Here we illustrate our formalism in the tripartite setting, relating it to U ⊗ U ⊗ U-invariant PPT states [15] and a recently introduced class of positive maps [16]. In particular, we illustrate that the considered maps correspond to elements of C[S n ] and WBA(n, d, k), motivating us to study the maps generated by these algebras further.…”

“…With this section we want to provide the reader of two examples to illustrate the connection of our formalism with well-known examples of existing tripartite maps, such as the ones appearing in Ref. [7], and the tripartite states of Ref. [6].…”

“…For the values of α and β satisfying conditions 1 and 2, the operator P (α, β) is block-positive in the bipartition 15) is a witness of entanglement in the bipartition 1|23. That is, these are the points for which the map is positive according to condition 2 of [7], and for which the operator P (α, β) is not positive semidefinite.…”
