Calculations for the Practical Applications of Quadratic Helicity in MHD

Petr M. Akhmet'ev, Simon Candelaresi, Alexandr Yu Smirnov

For the quadratic helicity we present a generalization of the Arnol'd inequality which relates the magnetic energy to the quadratic helicity, which poses a lower bound. W…

Quantifying the Tangling of Trajectories Using the Topological Entropy

Simon Candelaresi, David Ian Pontin, Gunnar Hornig

We present a simple method to efficiently compute a lower limit of the topological entropy and its spatial distribution for two-dimensional mappings. These mappings could represent…
