Boundary singularities of solutions to elliptic viscous Hamilton-Jacobi equations

preprint2012arXivOpen access

Abstract

We study the boundary value problem with measures for (E1) $-\Gd u+g(|\nabla u|)=0$ in a bounded domain $\Gw$ in $\BBR^N$, satisfying (E2) $ u=\gm$ on $\prt\Gw$ and prove that if g∈L1(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
