On the single-field formulation in magnetostatics

We systematically discuss the equivalence of two variational formulations of magnetostatics, in terms of magnetization and magnetic field, on the one hand, and the single-field formulation using only magnetic induction. To demonstrate that this link is stable also when the magnet...

Revisiting the Stability of the Ingleton Inequality: A Tropicalization-Free Approach

The classical Ingleton inequality is known to hold for entropic points under specific exact conditional independence constraints. Recently, Matveev and Romashchenko (2026) investigated the stability of these implications, quantifying the extent to which the Ingleton inequality ca...
