Abstract

We investigate the global nonlinear stability of the non-cutoff Vlasov-Yukawa-Boltzmann (VYB) system with moderately soft potentials γ+2s(0,2) and all physically relevant singularity parameter s(0,1). Building upon the foundational framework established in Chaturvedi's work [Ann. PDE, 7(2021), no.2, Paper No. 15, 104 pp.], we demonstrate the global nonlinear stability of the VYB system near vacuum by leveraging space-time weights and employing commuting vector fields to achieve integrable time decay for the nonlinear terms. This extends the existence result in Choi and Ha's work [Acta Math. Sci. Ser. B (Engl. Ed.) 35 (2015), no. 4, 887–905.] to angular non-cutoff cases.
真空附近无角截止的Vlasov-Yukawa-Boltzmann系统
研究了具有中软势γ+2s∈(0,2)和所有物理相关奇点参数s∈(0,1)的非截止VYB系统的全局非线性稳定性。在Chaturvedi的工作中建立的基本框架的基础上[Ann。PDE, 7(2021), no。2,论文No. 15, 104 pp.],我们利用空时权值和交换向量场来实现非线性项的可积时间衰减,证明了VYB系统在真空附近的全局非线性稳定性。这扩展了Choi和Ha的工作中的存在性结果[数学学报]。科学。爵士。B(英格兰。编辑)35 (2015),no。4, 887 - 905。]到有角度的非截止情况。
