Abstract:In this paper, we study the boundarybehavior of large solutions for non-divergence structureelliptic equations of second order.We show that the asymptotic behaviour of largesolutions near the boundary by a perturbation methods,Karamata regular variation theory, comparisonprinciple and constructingappropriate super-solutions and sub-solutions, underfurther assumptions on the weight function and thenonlinear function.
