In this paper,by using the method of moving planes,we are conced with the symmetry and monotonicity of positive solutions for the fractional Hartree equation.
In this work,we study the Cauchy problem for the radially symmetric spatially homogeneous Boltzmann equation with Debye-Yukawa potential.We prove that this Cauc
We prove the global existence of classical solutions to a fluid-particle interaction model in R3,namely,compressible Navier-Stokes-Smoluchowski equations,when t
The purpose of this work is to study the global existence and asymptotic behavior of solutions to a coupled reaction-diffusion system describing epidemiological
This paper concs the Cauchy problem of the 3D generalized incompressible magneto-hydrodynamic (GMHD) equations.By using the Fourier localization argument and th
