Quasi-periodic bifurcations of invariant circles in low-dimensional dissipative dynamical systems
This paper first summarizes the theory of quasi-periodic bifurcations for dissipative dynamical systems. Then it presents algorithms for the computation and continuation of invariant circles and ofExpand
Subordinate Sil'nikov bifurcations near some singularities of vector fields having low codimension
A specific singularity of a vector field on R 3 is considered, of codimension 2 in the dissipative case and of codimension 1 in the conservative case. In both contexts in generic unfoldings theExpand
Families of quasi-periodic motions in dynamical systems depending on parameters
One of the central topics in the qualitative theory of differential equations is the study of invariant submanifolds. A number of general theorems establishing the existence and/or persistence andExpand

Invariant circles in the Bogdanov-Takens bifurcation for diffeomorphisms
We study a generic, real analytic unfolding of a planar diffeomorphism having a fixed point with unipotent linear part. In the analogue for vector fields an open parameter-domain is known to exist,Expand
