这篇论文是我们最近论文的续篇。我们将考虑具有标度不变、质量和耗散以及功率非线性的波动模型的半线性柯西问题。我们的目标是研究质量系数和耗散项之间的相互作用,以证明小数据能量解(在时间上)的全局存在性,假设数据在L2尺度上具有适当的正则性,并且数据具有附加的L1正则性。为了处理非线性部分的这种二语规律性,我们将开发和使用一些调和分析工具。
This paper is a continuation of our recent paper . We will consider the semi‐linear Cauchy problem for wave models with scale‐invariant time‐dependent mass and dissipation and power non‐linearity. The goal is to study the interplay between the coefficients of the mass and the dissipation term to prove global existence (in time) of small data energy solutions assuming suitable regularity on theL2scale with additionalL1regularity for the data. In order to deal with thisL2regularity in the non‐linear part, we will develop and employ some tools from Harmonic Analysis.
