Given a quasiconformal mapping f:Rn→ Rn with n ≥ 2,we show that the(un-)boundedness of the composition operator Cf on the spaces Qα(Rn)depends on the index
By introducing the space with weak mixed norms,weak type estimates of two kinds of multilinear fractional Hausdorff operators RΦ,→β and SΦ,β on Lebesgue sp
I will talk about some recent results concerning the global well-posedness of the incompressible Navier-Stokes equations,the inhomogeneous Navier-Stokes equatio
Let M be the multilinear maximal function and →b =(b1,· · ·,bm)be a collection of locally integrable functions.Denote by M→b and [→b,M] the maximal commut
