AbstractWe consider the following free boundary problem in an unbounded domain Ω in two dimensions: Δpu=0 in Ω, u=0,∂u∂n=g0 on J0, u=1,∂u∂n=g1 on J1, where ∂Ω=J0∪J1. We prove that if 0<u<1 in Ω, Ji is the graph of a function in Cloc1,α(R) and gi is a constant for each i=0,1, then the free boundary ∂Ω must be two parallel straight lines and the solution u must be a linear function. The proof is based on maximum principle
