Fig. 24From: Fast–Slow Bursters in the Unfolding of a High Codimension Singularity and the Ultra-slow Transitions of ClassesSaddle and cusp cases. Hysteresis-loop and slow-wave paths for A the saddle case, time forward; B the cusp case, time reversed; C the saddle case, time reversed, and D the cusp case, time forward. Existence of classes is the same for A and B, and for C and D Back to article page
