Abstract:
In this paper, we investigate the following mixed boundary value problem of an elliptic systems: δ^2Δu = u(V + g1(u^2)-α1),δ^2Δw = w(-V + g2(w^2)-α2 )- λ^2ΔV = u^2 - w^2 - C,u=u0,w-w0,V =V0, on ΓD,δu/δv=δw/δv=δV/δv=0,on ΓN, where uo,wo,Vo∈H^1(Ω)∩L^∞(Ω), u0,w0≥0, in Ω , V is the unit outward normal to ΓN. We prove the existence and uniqueness of the solution of the system.[著者文摘]
