A sharp Hölder estimate for elliptic equations in two variables
نویسنده
چکیده
We prove a sharp Hölder estimate for solutions of linear two-dimensional, divergence form elliptic equations with measurable coefficients, such that the matrix of the coefficients is symmetric and has unit determinant. Our result extends some previous work by Piccinini and Spagnolo [7]. The proof relies on a sharp Wirtinger type inequality.

On the best Hölder exponent for two dimensional elliptic equations in divergence form
We obtain an estimate for the Hölder continuity exponent for weak solutions to the following elliptic equation in divergence form: div(A(x)∇u) = 0 in Ω, where Ω is a bounded open subset of R and, for every x ∈ Ω, A(x) is a matrix with bounded measurable coefficients. Such an estimate “interpolates” between the well-known estimate of Piccinini and Spagnolo in the isotropic case A(x) = a(x)I , wh...
متن کاملCompactness Methods for Hölder Estimates of Certain Degenerate Elliptic Equations
In this paper we obtain the interior C regularity of the quasilinear elliptic equations of divergence form. Our basic tools are the elementary local L estimates and weak Harnack inequality for second-order linear elliptic equations, and the compactness method.
متن کاملOn Beltrami equations and Hölder regularity
We estimate the Hölder exponent α of solutions to the Beltrami equation ∂f = μ∂f , where the Beltrami coefficient satisfies ‖μ‖∞ < 1. Our estimate improves the classical estimate α ≥ ‖Kμ‖ , where Kμ = (1 + |μ|)/(1 − |μ|), and it is sharp, in the sense that it is actually attained in a class of mappings which generalize the radial stretchings. Some other properties of such mappings are also prov...
متن کاملHölder Estimates for Solutions of Degenerate Nondivergence Elliptic and Parabolic Equations
We deal with a class of nondivergence type elliptic and parabolic equations degenerating at the coordinate hyperplanes. Assuming that the degeneration is coordinatewise and varies regularly, we prove the Hölder continuity of solutions. Also, the approximative solutions are considered. §

In this paper, we consider the following type of non-local (pseudo-differential) operators L on Rd: Lu(x) = 1 2 d ∑ i,j=1 ∂ ∂xi ( aij(x) ∂ ∂xj ) + lim ε↓0 ∫ {y∈Rd: |y−x|>ε} (u(y) − u(x))J(x, y)dy, where A(x) = (aij(x))1≤i,j≤d is a measurable d × d matrix-valued function on Rd that is uniformly elliptic and bounded and J is a symmetric measurable non-trivial nonnegative kernel on Rd × Rd satisfy...
