Invariant manifolds of maps and vector fields with nilpotent parabolic tori

Clara Cufí-Cabré, Ernest Fontich

We consider analytic maps and vector fields defined in $R^{2} \times T^{d}$ , having a $d$ -dimensional invariant torus $T$ . The map (resp. vector field) rest…

Functional shift-induced degenerate transcritical Neimark-Sacker bifurcation in a discrete hypercycle

E. Fontich, A. Guillamon, J. Perona +1

In this article we investigate the impact of functional shifts in a time-discrete cross-catalytic system. We use the hypercycle model considering that one of the species shifts fro…
