It follows easily that the equation (1)' F(ajl) = G(Du, D2u) = +(x) > 0 is elliptic at every admissible function u. Furthermore, relying on the results of Section 3 of [3] we see that F is a concave function of the matrix (ail) and hence G is a concave function in its dependence on the symmetric matrix D2u.

Second-Order Elliptic Equation with Singularities
https://www.hindawi.com/journals/ijde/2020/4589864
Equation ( 1) is one of the nonlinear second-order equations involving the singular term and with critical Sobolev growth. Such problem arises from various fields of geometry and physics. There are many results for second-order elliptic equations, but most of them are focused on bounded domains of or on compact Riemannian manifold , see [ 1 ...

Second order elliptic partial di erential equations are fundamentally modeled by Laplace’s equation u= 0. This thesis begins with trying to prove existence of a solution uthat solves u= fusing variational methods. In doing so, we introduce the theory of Sobolev spaces and their embeddings into Lp and Ck; . We then

THE HARNACK INEQUALITY FOR SECOND-ORDER ELLIPTIC EQUATIONS WITH DIVERGENCE-FREE DRIFTS∗ MIHAELA IGNATOVA†, IGOR KUKAVICA‡, AND LENYA RYZHIK§ Abstract. We consider an elliptic equation with a divergence-free drift b. We prove that an inequality of Harnack type holds under the assumption b∈Ln/2+δ where δ>0. As an application
