报告题目: Applications of the Wiener algebra to the Boltzmann theory on torus

报告摘要：The Wiener algebra is the space of all integrable functions on the torus whose Fourier series are absolutely convergent.In this talk,I will present applications to the Wiener algebra to the non-cutoffff Boltzmann equation on torus,in order to develop a theory in perturbation framework around global Maxwellians for the global existence,Gevrey regularity and grazing collision limit of solutions to the Cauchy problem.
