Justification and structure- and asymptotic-preserving discretizations of a hyperbolized Cahn-Hilliard equation
Jan Giesselmann, Fabio Leotta, Hendrik Ranocha +1
We study a hyperbolic approximation ("hyperbolization") of the Cahn-Hilliard (CH) equation, originally proposed by Dhaouadi, Dumbser, and Gavrilyuk (2025, DOI: 10.1098/rspa.2024.06…

Identification of minimal number of measurements allowing synchronization of a nodal observer for the wave equation
Jan Giesselmann, Teresa Kunkel
We study a state estimation problem for a linear hyperbolic system on networks with eigenvalues with opposite signs. The system can be seen as a simplified model for ga…
