We prove the existence of a new class of entire, positive solutions for the classical elliptic problem Δu−u+up=0 in R2, when p>2. The solutions we construct are obtained by perturbing the function

Regularity criterion of weak solutions to the 3D Navier-Stokes equations via two velocity components 总被引:1,自引:0,他引:1
This paper is concerned with the regularity criterion of Leray-Hopf weak solutions to the 3D Navier-Stokes equations with respect to Serrin type condition on two velocity filed components. It is shown that the weak solution u=(u1,u2,u3) is regular on (0,T] if there exist two solution components, for example, u2 and u3, satisfying the condition
