Kurzfassung englisch:
A previously developed algebraic approach to proving entropy production inequalities
is extended to deal with radially symmetric solutions for a class of higher-order diffusion equations
in multiple space dimensions. In application of the method, novel a priori estimates are derived for
the thin-film equation, the fourth-order Derrida-Lebowitz-Speer-Spohn equation, and a sixth-order
quantum diffusion equation.
