Local solutions for a coupled system of Kirchhoff type Original Research Article

We investigate the existence of local solutions of the following coupled system of Kirchhoff equations subject to nonlinear dissipation on the boundary: equation(∗∗ Turn MathJax on ) View the MathML source|u″−M1(t,‖u(t)‖2,‖v(t)‖2)△u=0in Ω×(0,∞),v″−M2(t,‖u(t)‖2,‖v(t)‖2)△v=0in Ω×(0,∞),u=0,v=0on Γ0×]0,∞[,∂u∂ν+δ1h1(u′)=0on Γ1×]0,∞[,∂u∂ν+δ2h2(u′)=0on Γ1×]0,∞[.

By applying the Galerkin method with a special basis for the space where lie the approximations of the initial data, we obtain local solutions of the initial-boundary value problem for (∗).
