Conditional regularity for the Navier-Stokes-Fourier system with Dirichlet boundary conditions
We consider the Navier–Stokes–Fourier system with the inhomogeneous boundary conditions for the velocity and the temperature. We show that solutions emanating from sufficiently regular data remain regular as long as the den...

Boundary regularity of flows under perfect slip boundary conditions
We investigate boundary regularity of solutions of generalized Stokes equations. The problem is complemented with perfect slip boundary conditions and we assume that the nonlinear elliptic operator satisfies non-standard I center do...

A note on regularity and positive definiteness of interval matrices
We present a sufficient regularity condition for interval matrices which generalizes two previously known ones. It is formulated in terms of positive definiteness of interval matrices. Comparing it with Beeck?s strong regularity...

On Conditional Regularity for the MHD Equations via Partial Components
In this paper we establish some new regularity criteria for the three dimensional incompressible MHD equations via partial components of velocity and magnetic fields. Moreover, some Prodi-Serrin type regularity conditions a...

Regularity criteria for the Navier-Stokes equations in terms of the velocity direction and the flow of energy.
We deal with the conditional regularity of the weak solutions to the Navier to bounded domains with Navier and Navier-type boundary conditions. We further prove an optimal regularity criterion in terms of u⋅del|u|λ...
