Abstract
We prove a comparison principle for unbounded weak sub/super solutions of the equationλuâdiv(A(x)Du)=H(x,Du) in Ω where A(x) is a bounded coercive matrix with measurable ingredients, λâ¥0 and ξâ¦H(x,ξ) has a super linear growth and is convex at infinity. We improve earlier results where the convexity of H(x,â
) was required to hold globally.
