Abstract
In the paper we study the damped half-linear partial differential equationdiv(A(x)‖∇u‖p−2∇u)+〈b→(x),‖∇u‖p−2∇u〉+c(x)|u|p−2u=0. Using radialization method we derive general oscillation results which allow to deduce new oscillation criteria for this equation from oscillation criteria for ordinary differential equations. Using careful radialization we improve several known oscillation criteria.
