WebMar 1, 2024 · Our interesting observation is the abrupt behavior of the system just when the theory touches the Higuchi bound [17], where the constraint structure of the system has a completely different character. Exactly at the Higuchi bound, one chain of constraints with four second class elements changes to a first class chain with three elements.
