abstract
We give a proof of the Erd\H{o}s-Ko-Rado Theorem using the Borel Fixed Point Theorem from algebraic group theory. This perspective gives a strong analogy between the Erd\H{o}s-Ko-Rado Theorem and (generalizations of) the Gerstenhaber Theorem on spaces of nilpotent matrices.

Core-surface kinematic control of polarity reversals in advanced geodynamo simulations
Polarity reversals in geodynamo simulations are triggered when stable stratification at the top of the core weakens subsurface upwellings, a kinematic control that decouples reversals from the interior force balance.
