摘要

Much of the existing, rigorous proofs for the occurrence of chaos in PDEs are in one space dimension. Very few results are known for problems in multi-dimensional settings. The study of chaotic vibrations for multi-dimensional PDEs due to nonlinear boundary conditions is challenging. Not only the equation itself but the geometric shape of the domain matters in analyzing the complex dynamics.
