Abstract

We study the boundary value problem with measures for (E1) \Gdu+g(u)=0-\Gd u+g(|\nabla u|)=0 in a bounded domain \Gw\Gw in \BBRN\BBR^N, satisfying (E2) u=\gm u=\gm on \prt\Gw\prt\Gw and prove that if gL1(1,;t(2N+1)/Ndt)g\in L^1(1,\infty;t^{-(2N+1)/N}dt) is nondecreasing (E1)-(E2) can be solved with any positive bounded measure. When g(r)rqg(r)\geq r^q with q>1q>1 we prove that any positive function satisfying (E1) admits a boundary trace which is an outer regular Borel measure, not necessarily bounded. When g(r)=rqg(r)=r^q with $1
