urn:hdl:10230/36166 A Parabolic quasilinear problem for linear growth functionals Andreu, Fuensanta Caselles, Vicente Mazón, José Linear growth functionals Nonlinear parabolic equations Accretive operators Nonlinear semigroups We prove existence and uniqueness of solutions for the Dirichlet problem for quasilinear parabolic equations in divergent form for which the energy functional has linear growth. A typical example of energy functional we consider is the one given by the nonparametric area integrand f(x,ξ)=√1+∥ξ∥2, which corresponds with the time-dependent minimal surface equation. We also study the asymptotic behaviour of the solutions. The first and third authors have been partially supported by the Spanish DGICYT, Project PB98-1442.
