Long-time Behaviour of DLRA for SDEs
Jianhai Bao, Haitao Wang, Yue Wu
We study dynamical orthogonal (DO) approximations of stochastic differential equations and investigate their long-time behaviour. The DO formulation represents the solution by a lo…

Space-time structure and particle-fluid duality of solutions for Boltzmann equation with hard potentials
Yu-Chu Lin, Haitao Wang, Kung-Chien Wu
We study the quantitative pointwise behavior of solutions to the Boltzmann equation for hard potentials and Maxwellian molecules, which generalize the hard sphere case introduced b…

3D hard sphere Boltzmann equation: explicit structure and the transition process from polynomial tail to Gaussian tail
Yu-Chu Lin, Haitao Wang, Kung-Chien Wu
We study the Boltzmann equation with hard sphere in a near-equilibrium setting. The initial data is compactly supported in the space variable and has a polynomial tail in the micro…
