Existence of unstable manifolds for a certain class of delay differential equations. <i>Electronic Journal of Differential Equations, 2002</i>(32), pp. 1-13.1072-6691https://hdl.handle.net/10877/12280We prove a theorem for unstable manifolds in a differential equation with a state-dependent delay. Although the equation cannot be formally linearized, we find an associated linear delay equation whose dynamics are qualitatively similar near the unstable manifold. Our proof relies upon estimates of the derivative of a trajectory on the unstable manifold near equilibrium.Text13 pages1 file (.pdf)enAttribution 4.0 InternationalInvariant manifoldsFunctional differential equationsArticle
