報告人簡介：馮兆生，美國德克薩斯大學RGV分校數學與統計學院終身教授，主要研究方向有非線性分析,分支和混沌理論,數學物理問題,數值計算和生物數學等。曾于2015年和2021年兩度獲得德克薩斯大學杰出成就獎。

觀點綜述：In this talk, we consider the one-, two- and three-dimensional wave equation with van der Pol type conditions. The symmetric nonlinearities of van der Pol type are proposed at the two boundary endpoints, which can cause the energy of the system to rise and fall within certain bounds. Qualitative and numerical techniques are developed to tackle the cubic nonlinearities and the chaotic regime is determined. Numerical simulations and visualizations of chaotic vibrations are illustrated by computer graphics.
