چکیده

We present some new regularity criteria for suitable weak solutions of magnetohydrodynamic equations near boundary in dimension three. We prove that suitable weak solutions are Hölder continuous near boundary provided that either the scaled L x,t-norm of the velocity with 3/p+ 2/q ≤ 2, 2 < q <∞, or the scaled L x,t-norm of the vorticity with 3/p+ 2/q ≤ 3, 2 < q <∞ are sufficiently small near the boundary.

M ay 2 00 5 Regularity criteria for suitable weak solutions of the Navier - Stokes equations near the boundary

We present some new regularity criteria for “suitable weak solutions” of the Navier-Stokes equations near the boundary in dimension three. We prove that suitable weak solutions are Hölder continuous up to the boundary provided that the scaled mixed norm L x,t with 3/p + 2/q ≤ 2, 2 < q ≤ ∞, (p, q) 6= (3/2,∞), is small near the boundary. Our methods yield new results in the interior case as well....

On Regularity Criteria in Conjunction with the Pressure of the Navier-Stokes Equations

We present new regularity criteria involving the integrability of the pressure for the Navier-Stokes equations in bounded domains with smooth boundaries. We prove that either if the pressure belongs to L x,t with 3/γ + 2/q ≤ 2 and 3/2 < γ ≤ ∞ or if the gradient of the pressure belongs to L x,t with 3/γ+2/q ≤ 2 and 1 < γ ≤ ∞, thenweak solutions are regular. Local regularity criteria in terms of ...

Interior Regularity Criteria for Suitable Weak Solutions of the Navier-Stokes Equations

We present new interior regularity criteria for suitable weak solutions of the 3-D Navier-Stokes equations: a suitable weak solution is regular near an interior point z if either the scaled L p,q x,t -norm of the velocity with 3/p + 2/q ≤ 2, 1 ≤ q ≤ ∞, or the L p,q x,t -norm of the vorticity with 3/p + 2/q ≤ 3, 1 ≤ q < ∞, or the L p,q x,t -norm of the gradient of the vorticity with 3/p + 2/q ≤ ...
