Invariance and symmetry in a year-class model

    Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

    Abstract

    In this note we reveal some of the special structure of a year-class model. We formulate a certain parameter symmetry and compute the characteristic equation at the unique nontrivial equilibrium. In the case of equal sensitivity we derive phase-amplitude equations and show the existence of an invariant manifold.
