In this paper we study the Dirichlet problem for a class of nonlinear elliptic equations in the form A(u) = H (x, u, Du)+g (x, u), where the principal term is a Leray-Lions operator defined on W 1,p 0 ( ). Comparison results are obtained between the rearrangement of a solution u of Dirichlet problem

The main purpose of this paper is to prove that there is a homomorphism from the group of primitive points on an elliptic curve given by an equation \(Y^{2}=X^{3}+a_{2} X^{2}+a_{4} X+a_{6}\) to the ideal class group of the order \(\mathbb{Z}+\mathbb{Z} \sqrt{a_{6}}\). Two applications are given. Fir

First we define relations between the u = (s\* + s + 1) (s + 1) flags (point-line incident pairs) of a finite projective plane of order s. Two flags a E (p, 1) and b = (p', l'), where p and p' are two points and 1 and 1' are two lines of the projective plane, are defined to
