Shadowing of non-transversal heteroclinic chains Delshams Valdés, Amadeu Simon, Adriá Zgliczynski, Piotr Àrees temàtiques de la UPC::Matemàtiques i estadística Schrödinger equation Differential equations Covering relations heteroclinic chain non-transversal intersection s hadowing Equacions diferencials ordinàries Schrödinger, Equació de Classificació AMS::37 Dynamical systems and ergodic theory::37J Finite-dimensional Hamiltonian, Lagrangian, contact, and nonholonomic systems © 2017 Elsevier Inc. We present a new result about the shadowing of non-transversal chain of heteroclinic connections based on the idea of dropping dimensions. We illustrate this new mechanism with several examples. As an application we discuss this mechanism in a simplification of a toy model system derived by Colliander et al. in the context of cubic defocusing nonlinear Schrödinger equation.
