Mapping between D _i and Ƶ ( D _i ). (a) Mapping of D₇ and its adjacent domains in Fig. 2 into the elements of Ƶ(D₇). The empty circles on the boundary of Ƶ(D₇) denote the candidate exit points. (b) The filled circles denote the exit points from Ƶ(D₇), whereas the empty circles denote unstable stationary points that correspond to possible entrance points to Ƶ(D₇). The single-headed arrows denote the direction of change of Z _l , ∀l ∈ ℒ _F in a neighborhood of the exit points.
