On a result of C.V. Coffman and W.K. Ziemer about the prescribed mean curvature equation
We produce a detailed proof of a result of C.V. Coffman and W.K.
Ziemer [1] on the existence of positive solutions of the Dirichlet problem for
the prescribed mean curvature equation
-div$(\nablau/\sqrt(1+|\nablau|^2)=\lambdaf(x,u)$ in $\Omega,$ $u=0$ on $\partial\Omega$
assuming that $f$ has a superlinear behaviour at $u = 0$.
