Local strong solutions to a quasilinear degenerate fourth-order thin-film equation
Christina Lienstromberg, Stefan Müller
We study the problem of existence and uniqueness of strong solutions to a degenerate quasilinear parabolic non-Newtonian thin-film equation. Originating from a non-Newtonian Navier…

Planar S-systems: Global stability and the center problem
Balázs Boros, Josef Hofbauer, Stefan Müller +1
S-systems are simple examples of power-law dynamical systems (polynomial systems with real exponents). For planar S-systems, we study global stability of the unique positive equili…

-characterization of symplectic and contact embeddings and Lagrangian rigidity
Stefan Müller
We present a novel -characterization of symplectic embeddings and diffeomorphisms in terms of Lagrangian embeddings. Our approach is based on the shape invariant, which was di…
