Topological structures for periodic orbits of graph maps via suspension

Objetivo



Research objectives and content
The proposed research programmeis to understand some structures for the set of periodic orbits for continuous maps of a graph into itself. The goal is to give a general framework where all the previously known cases would be included. Some particular cases have been intensively studied '` la Sharkovskii', such as the interval circle and tree maps. The case of surface homeomorphisms has been treated via special graph maps and should also be a particular case. The new ingredient in this programmeis to consider graph maps via the 'suspension operation' for which I gave a combinatorial construction in my PhD thesis. This operation gives at the same time a 2-dimensional complex and a semi-flow. A periodic orbit of a graph map gives rise to both an element of the fundamental group of this complex and a periodic orbit of the semi-flow. The initial dynamical problem can then be studied by standard Algebraic technics and, for instance, a generalization of the notion of 'braid type' is expected. Training content (objective, benel it and expected impact)
Barcelona is a perfect place for such a programmeto be developped since the dynamical system group is very active, as well as the Algebraic topology group.
