| 題目： | Energy estimates for Klein-Gordon type models with oscillations |
| 要旨： | The aim of this talk is to present some energy estimates for Klein-Gordon equations with time-dependent mass. In dependence on the conditions on the mass term some results of generalized energy conservation and blow-up behavior of the energy for large times will be discussed. The starting point are statements about generalized energy conservation for a scale-invariant model case. Based on these results the influence of oscillations in interplay with a decreasing term will be investigated. Conclusively, there will follow some remarks about scattering results for Klein-Gordon equations with variable mass, i.e., the behavior of the energy is in some sense similar to the behavior of the energy of the free wave equation for large times. |
