Aim and Scope: The study of phenomena of the real world, in recent years, is carried on through a mathematical simulation which captures their behaviour, characteristics and properties. If, during its evolution, the phenomena show a dependency on the previous history, then the mathematical models which best simulate the phenomena are Integral Equations, whose hereditary character makes difficult both the theoretical study and the resolution process. In particular, Volterra Integral Equations appear in the study of many phenomena which are important in applied sciences, such as population dynamics, diffusion of an epidemic, neural networks, and so on. For most of these models, it is important to develop both new efficient numerical methods, and mathematical software to obtain numerical solutions for the comprehension of the phenomena during its evolution in time, and to collect informations on the problem. Aim of this Workshop is to provide a forum both for expert researchers in this topic, and for researchers of closed areas, to present and discuss ideas, theories and applications.

In the Dynamical Systems group there is a vacancy for a PhD Research position for the project Stability, Bifurcations and Stabilisation of Invariant Sets in Differential Inclusions * /Institute of Mathematics and Computing Science University of Groningen/ * Topics of research Discontinuities are present in a wide variety of systems; e.g. friction in mechanical systems, diodes in electrical circuits or switching control systems. Models of such systems are commonly formulated as differential equations with discontinuous right-hand sides. Such systems can be formulated as differential inclusions with a set-valued right-hand side when no state-jumps occur; these systems are commonly called Filippov systems. Equilibria, periodic and quasi-periodic solutions of differential inclusions represent important classes of limit solutions for such systems. The equilibria may range from one or multiple isolated equilibrium points, either on or outside the discontinuity surfaces, to equilibrium sets located on the discontinuity surface(s). Likewise, the (quasi-) periodic solutions can either lie entirely in the smooth domain of the state-state space or hit (or partially slide along) the discontinuity surface. The stability properties of these limit solutions largely influence the global dynamics of the system. Therefore, the first goal of the project is the development of a stability theory for such limit solutions. For details see http://www.math.rug.nl/~broer or http://www.ndns.nl This is a double project with a counterpart at Eindhoven University with another PhD research project under Prof Henk Nijmeijer, see http://w3.wtb.tue.nl/nl/people_pages/?&script=showemp.php&no_cache=1&pid=953 The Groningen PhD research, under my direction, focusses on the mathematical description and classification of the generic dynamics, the bifurcations, etc.. The Eindhoven PhD is directed more towards control aspects. However, we plan a close interaction, e.g., at the level of case studies.
