论文摘要

对于ZND模型,我们在下游方面还显示了任意增长的加权规范的奇异性形成。另一方面,对于MAJDA模型,我们为适当的加权规范建立了一组能量估计,这不仅意味着在任意振幅的波浪附近的奇点不形成,而且还意味着对小振幅的全渐近轨道稳定性。

For the ZND model, we show also singularity formation on the downstream side for arbitrary exponentially-growing weighted norms. For the Majda model on the other hand, we establish for appropriate such weighted norms a set of energy estimates implying not only non-formation of singularities near waves of arbitrary amplitude but also full asymptotic orbital stability for small-amplitude ones.
