摘要:We are concerned with the behaviour of weak solutions of the Navier-Stokes system around possible singularities on the boundary. We show that a weak solution locally belonging to some Lebesgue space cannot blowup there.

摘要:We study questions of solvability for operators of the form p(x,D)+b, where p(x,ξ) is a real quadratic form and bεC. As one consequence, we obtain a necessary and sufficient condition for the local solvability of operators of the form L= near the critical point x=0, and prov...

摘要:In this paper, we show that the strict mononicity of the eigen-values of an uniformly elliptic operator of second order is equivalent to a unique continuation property.
