Strong Lyapunov functions for rough systems
Luu Hoang Duc, Jürgen Jost
We extend the Lyapunov function technique, a fundamental tool for investigating asymptotic stability and existence of attractors for ordinary differential equations, by introducing…
Boundary partial regularity for a class of Dirac-harmonic maps
Jürgen Jost, Jingyong Zhu
In this paper, we prove the boundary partial regularity for a class of coupled Dirac-harmonic maps satisfying a certain energy monotonicity inequality near the boundary.
Dirac-harmonic maps with trivial index
Jürgen Jost, Linlin Sun, Jingyong Zhu
For a homotopy class of maps between a closed Riemannian manifold and a general manifold , we want to find a Dirac-harmonic map with the map component in the given hom…
A mathematical model for cognitive structures and processes underlying innovations
Jürgen Jost, Massimo Warglien
Business innovations are often arising from new combinations of pre-existing systems into new ones, coherently assembling features from their sources. We propose an abstract mathem…
