Objective
The network will establish links and collaborations between different partners of the teams at a moment when there is a special need at the European level to promote the training of young researchers in the research area covered by the project. Indeed, for the time being, each participant of the network has a great practice of several tools and/ or problems with which the other participants are less familiar. The lack of collaboration between the participants delays the development of these themes. The training of young specialists in these research areas will be organized via doctoral courses, workshops and seminars organized by the network. The young researchers will not only learn new techniques and problems but also start early fruitful collaborations with others mathematicians working in the same research area. The postdoctoral positions would allow to enlarge the scientific horizons of young researchers and stimulate them to start new challenging themes of research.
