报告摘要:

        In this talk, we consider the one-, two-and three-dimensional wave equation on the unit interval [0, 1] with the initial boundary condition. This nonlinear boundary condition behaves like a van der Pol oscillator, causing the total energy to rise and fall within certain bounds regularly or irregularly. We formulate the problem in terms of an equivalent first order hyperbolic system and use the method of characteristics to derive a nonlinear reflection relation caused by the nonlinear boundary conditions. Numerical simulations and visualizations of chaotic vibrations are illustrated by computer graphics.
