PARABOLIC Lp DIRICHLET BOUNDARY VALUE PROBLEM AND VMO-TYPE TIME-VARYING DOMAINS [PDF]
We prove the solvability of the parabolic Lp Dirichlet boundary value problem for 1 < p ≤1 for a PDE of the form ut = div(Aru) + B · ru on time-varying domains where the coefficients A = [aij (X, t)] and B = [bi] satisfy a certain natural small ...

Holder continuity for vector-valued minimizers of quadratic functionals
In this article we give a sufficient condition for interior everywhere Holder continuity of weak minimizers of a class of quadratic functionals with coefficients $A_{ij}^{\alpha\beta}(\cdot,u)$ belonging to the VMO-class, uniformly with respect to $u\

The cauchy-dirichlet problem for parabolic equations with VMO coefficients
The paper deals with the \(W^{2,1}_p(Q_T)\)-regularity and solvability of the Cauchy-Dirichlet problem for linear second-order, uniformly parabolic equations of the form \[ {\mathcal L}u\equiv \partial_tu- \sum_{i,j=1}^n a_{ij}(x)u_{x'_ix'_j}+ \sum_{i=1}^n b_i(x)u_{x'_i} +cu=f \] with \(x=(x',t)\) lying in the cylinder \(Q_T=\Omega\times(0,T)\subset ...

Morrey estimates for a class of noncoercive elliptic systems with VMO-coefficients
We consider a non-coercive vectorial boundary value problem with non smooth coefficients and a drift term and we study the regularity of a solution u and its gradient in the framework of suitable Morrey spaces.

Mean oscillation gradient estimates for elliptic systems in divergence form with VMO coefficients
We consider gradient estimates for $H^1$ solutions of linear elliptic systems in divergence form $\partial_\alpha(A_{ij}^{\alpha\beta} \partial_\beta u^j) = 0$.

Bounds for elliptic operators in weighted spaces
Some estimates for solutions of the Dirichlet problem for second-order elliptic equations are obtained in this paper. Here the leading coefficients are locally VMO functions, while the hypotheses on the other coefficients and the boundary conditions ...

In this article, we consider quasi-linear elliptic systems in divergence form with discontinuous coefficients under controllable growth. We establish an optimal partial regularity of the weak solutions by a modification of A-harmonic approximation ...
