Oblique derivative problems for generalized Rassias equations of mixed type with several characteristic boundaries

open access: yesElectronic Journal of Differential Equations, 2009
This article concerns the oblique derivative problems for second-order quasilinear degenerate equations of mixed type with several characteristic boundaries, which include the Tricomi problem as a special case.

Behaviour near zero and near infinity of solutions to elliptic equalities and inequalities

open access: yesElectronic Journal of Differential Equations, 2001
Here we consider elliptic equations and inequalities involving quasilinear operators in divergence form and nonlinear lower order terms: $$-mathop{m div}left(mathcal{A}(x,u,abla u)ight) geq |x|^sigma u^Qquad(Q>0,sigma in mathbb{R}), $$ in dimension $Ngeq

Rate of convergence for solutions to Dirichlet problems of quasilinear equations

open access: yesElectronic Journal of Differential Equations, 2003
We obtain rates of convergence for solutions to Dirichlet problems of quasilinear elliptic (possibly degenerate) equations in slab-like domains. The rates found depend on the convergence of the boundary data and of the coefficients of the operator. These
