"A two-dimensional threshold surface of an excitable system is found as a set of threshold trajectories calculated step by step in cross-sections of the phase space. The method leads to a highly nonlinear boundary value problem that can be solved numerically with the use of adaptive multiple shooting and continuation methods. We demonstrate this technique by examining a model of a biochemical oscillator with two positive feedbacks. Generalization to arbitrary dimension is discussed."@en .
