Well-posedness results for triply nonlinear degenerate parabolic equations

Boris Andreianov, Mostafa Bendahmane, Kenneth K. Karlsen +1

We study the well-posedness of triply nonlinear degenerate elliptic-parabolic-hyperbolic problem $$ b(u)_t - {\rm div} \tilde{\mathfrak a}(u,\nablaϕ(u))+ψ(u)=f, \quad u|_{t=0}=u_0…
