Classification des cycles homoclines forces par symetrie dans R^4

Abstract : In this thesis we classify the
robust homoclinic cycles of $\mathbb{R}^4$ in presence of
symmetry. We limit our self to the case of a group G finite and,
without loss of generality, included in the orthogonal group
$O(4)$. We show that an infinite family of cycles exists; we give
the generators, a presentation and a detailed analysis of its
symmetry groups. The topology of the cycles is also studied.\\
These cycles
can
appear by a bifurcation from a trivial equilibrium so we can obtain
some
vector fields displaying such homoclinic cycles in the simplest
cases.
The numerical integration of such vector fields using the software
$\mathbf{Dstool}$ is possible; we visualize the projection of these cycles on
some planes.
