Abstract

For scalar non-linear elliptic equations, stationary solutions are defined to be critical points of a functional with respect to the variations of the domain. We consider u a weak positive solution of -Δu=uα in -Δu=uα in Ω ⊂ ℝn, which is stationary. We prove that the Hausdorff dimension of the singular set of u is less than n-2α+1/α-1, if α≥n+2/n-2. © 1993 Springer-Verlag.
