Original Announcement

This workshop will be devoted to the mathematical analysis of biochemical reaction networks arising in systems biology. Specifically, we are interested in classes of nonlinear dynamical systems that arise from biologically-relevant networks of chemical reactions, parametrized by rate constants that are usually unknown and difficult to measure. The nonlinearities in these systems have hindered mathematical analysis of network behavior, which has largely been studied by numerical simulation.

Recent developments have suggested that mathematical analysis of such networks may be feasible, using methods from computational algebra, algebraic geometry and dynamical systems. For instance, one class of dynamical systems, coming from mass-action kinetics, gives rise to polynomial dynamical systems. Here, the biologically-relevant steady states are the positive real solutions to a system of polynomial equations and from computational algebra and algebraic geometry have been used to shed light on steady-state behaviour. Difficult questions still remain regarding the transient dynamics and generalisations to non mass-action systems.

The primary aim of this workshop is to bring together mathematicians as well as researchers who are closer to the experimental side of systems biology, in order to formulate precise open problems and to explore appropriate mathematical methods to tackle them. We hope to sustain an open dialogue between theory and experiment, so that they may continue to stimulate each other. Among the problems we may consider initially are the following.
