摘要：

In the light of recent studies of Bogomol'nyi-Prasad-Sommerfeld (BPS) triple junctions in the Wess-Zumino model we describe techniques to construct infinite lattices using similar junctions. It is shown that while these states are only approximately locally BPS they are nevertheless stable to small perturbations, giving a stationary tiling of the plane.
