Gradient estimates for Stokes and Navier-Stokes systems with piecewise DMO coefficients

Jongkeun Choi, Hongjie Dong, Longjuan Xu

We study stationary Stokes systems in divergence form with piecewise Dini mean oscillation coefficients and data in a bounded domain containing a finite number of subdomains with $…

Gradient estimates for divergence form parabolic systems

Hongjie Dong, Longjuan Xu

We consider divergence form, second-order strongly parabolic systems in a cylindrical domain with a finite number of subdomains under the assumption that the interfacial boundaries…

Asymptotics of the stress concentration in high-contrast elastic composites

Haigang Li, Longjuan Xu

A long-standing area of materials science research has been the study of electrostatic, magnetic, and elastic fields in composite with densely packed inclusions whose material prop…

The Optimal Gradient Estimates for Perfect Conductivity Problem with C^{1,α} inclusions

Yu Chen, Haigang Li, Longjuan Xu

In high-contrast composite materials, the electric field concentration is a common phenomenon when two inclusions are close to touch. It is important from an engineering point of v…

Hessian estimates for non-divergence form elliptic equations arising from composite materials

Hongjie Dong, Longjuan Xu

In this paper, we prove that any strong solution to second-order non-divergence form elliptic equations is locally and piecewise when the leading c…

Gradient estimates for divergence form elliptic systems arising from composite material

Hongjie Dong, Longjuan Xu

In this paper, we show that weak solutions to divergence form elliptic systems are Lipschitz and piecewise provided that the leading coefficien…
