Classical and weak solutions for semilinear parabolic equations with Preisach hysteresis


Abstract. We consider the solvability of the semilinear parabolic differential equation \[\frac{\partial u}{\partial t}(x,t)- \Delta u(x,t) + c(x,t)u(x,t) = \mathcal{P}(u) + \gamma (x,t)\] in a cylinder \(D=\Omega \times (0,T)\), where \(\mathcal{P}\) is a hysteresis operator of Preisach type. We show that the corresponding initial boundary value problems have unique classical solutions. We further show that using this existence and uniqueness result, one can determine the properties of the Preisach operator \(\mathcal{P}\) from overdetermined boundary data.
Keywords: hysteresis, parabolic, inverse problem, uniqueness.
