Dynamics of the reversible Gray-Scott model and convergence to its irreversible limit
Philippe Laurençot, Christoph Walker
Well-posedness of a reversible variant of the Gray-Scott model is shown, along with the convergence of each trajectory to one of the two spatially homogeneous steady states. The pr…

Recovering Initial States in Certain Quasilinear Parabolic Problems from Time Averages
Bogdan-Vasile Matioc, Christoph Walker
The inverse problem of reconstructing the initial state in quasilinear parabolic equations from time averages is investigated. Under suitable regularity assumptions on the quasilin…

On the principle of linearized stability for quasilinear evolution equations in time-weighted spaces
Bogdan-Vasile Matioc, Lina Sophie Schmitz, Christoph Walker
Quasilinear (and semilinear) parabolic problems of the form with strict inclusion of the domains of the function $v\maps…
