Web4Email to [email protected] reaches the principal authors Abstract We present a new experimental-computational technology of inferring network models that predict the response of cells to perturbations and that may be useful in the design of combinatorial therapy against cancer. The WebPerturbation theory for PDEs is a part of the qualitative theory of differential equations. One of the most effective methods of perturbation theory is the normal form theory which consists of using coordinate transformations in order to describe the qualitative features of a given or generic equation.
