    Page de Garde On the existence, uniqueness and asymptotic behaviour of the solution of the non-linear kirchhoff model expanding domains.
    (UNIVERSITE MOULOUD MAMMERI DE TIZI-OUZOU, 2025) Lasfer , Fazia; Rapporteur : Benabidallah , Rachid
    In this thesis we study the global and decay solution for large size data of non-linear hyperbolic-parabolic equation of Kirchhoff type u_tt+μu_t-M ̃(∫_(Ω_t)▒|∇u|^2 dx)Δu=0 in Ω_t Where Ω_t={x∈ R^n:x=yσ(t),y∈Ω} with Ω being a bounded open domain in R^n, μ is a positive constant and σ(t) is a given suitable increasing positive function unbounded from above. The real function (M ) ̃is such that( M) ̃(ℷ)>0, M ̃(ℷ)≥0 for every ℷ ∈ [0,∞[
