A Singular Fold Model for Capacity-Constrained Dynamics

We study a minimal fast-slow model for capacity-constrained accumulation: a smooth saddle-node fast subsystem coupled to a slow field g(x) = α − βk/x, singular at the fold boundary x = 0. Variables are dimensionless. Two are kept distinct: the capacity margin μ = Q − V, and the s...
