报告摘要： In this talk, we are concerned with the description of global quantitative stability of wave equations with linear strong damping and linear or nonlinear weak damping. By giving some energy decay estimates, we obtain several conclusions about the continuous dependence of the global solution on the initial data and the coefficients of the strong damping term and linear or nonlinear weak damping term. This work also establishes a new idea to use the dissipative effect to obtain the better continuous dependence conclusions, which also reflect the dissipative properties of the solution. This is a collaborated work with Dr. Jiangbo Han at Harbin Engineering University/Inner Mongolia University, Dr. Chao Yang at AGH University of Science and Technology, Poland, and Professor Keyan Wang at Shanghai University of Finance and Economics.
