چکیده
An elliptic equation ∇· (F (∇u)) = f whose ellipticity strongly degenerates for small values of ∇u (say, F = 0 on B(0, 1)) is considered. The aim is to prove regularity for F (∇u). The paper proves a continuity result in dimension two and presents some applications.

Partial Hölder continuity for solutions of subquadratic elliptic systems in low dimensions
We consider weak solutions of second order nonlinear elliptic systems in divergence form under standard subquadratic growth conditions with boundary data of class C. In dimensions n ∈ {2, 3} we prove that u is locally Hölder continuous for every exponent λ ∈ (0, 1 − n−2 p ) outside a singular set of Hausdorff dimension less than n − p. This result holds up to the boundary both for non-degenerat...
متن کاملOptimal design problems in rough inhomogeneous media. Existence theory∗
This paper settles the existence question for a rather general class of convex optimal design problems with a volume constraint. In low dimensions, we prove the existence of an optimal configuration for general convex minimization problems ruled by bounded measurable degenerate elliptic operators. Under a mild continuity assumption on the medium, the free boundary is proven to enjoy the appropr...
متن کاملhigher integrability of the gradient in degenerate elliptic equations
We prove that under some global conditions on the maximum and the minimum eigenvalue of the matrix of the coefficients, the gradient of the (weak) solution of some degenerate elliptic equations has higher integrability than expected. Technically we adapt the Giaquinta-Modica regularity method in some degenerate cases. When the dimension is two, a consequence of our result is a new Hölder contin...
متن کاملModified F-Expansion Method Applied to Coupled System of Equation
A modified F-expansion method to find the exact traveling wave solutions of two-component nonlinear partial differential equations (NLPDEs) is discussed. We use this method to construct many new solutions to the nonlinear Whitham-Broer-Kaup system (1+1)-dimensional. The solutions obtained include Jacobi elliptic periodic wave solutions which exactly degenerate to the soliton solutions, triangu...
