Well-Posedness of Parabolic Differential and Difference Equations with the Fractional Differential Operator

The stable difference scheme for the approximate solution of the initial value problem du(t) dt + D 1 2 t u(t) + Au(t) = f(t), 0 < t < 1, u(0) = 0 for the differential equation in a Banach space E with the strongly positive operator A and fractional operator D 1 2 t is presented. The well-posedness of the difference scheme in difference analogues of spaces of smooth functions is established. In...

Well-posedness of parabolic equations containing hysteresis with diffusive thresholds

In the paper, we develop a theory of reaction-diffusion equations containing discontinuous hysteresis operator — the so-called non-ideal relay. The nonideal relay (or a bi-stable relay, or lazy switch) is the most basic, yet nontrivial hysteresis operator. The state (output) of the non-ideal relay switches from −1 to 1 when the input exceeds a threshold value x ∈ R and switches back to state −1...
