Minimal Supergravity and the supersymmetry of Arnold-Beltrami Flux branes
P. Fre', P. A. Grassi, L. Ravera +1
In this paper we study some properties of the newly found Arnold-Beltrami flux-brane solutions to the minimal supergravity. To this end we first single out the appropriate Fr…

Hyperinstantons, the Beltrami Equation, and Triholomorphic Maps
P. Fré, P. A. Grassi, A. S. Sorin
We consider the Beltrami equation for hydrodynamics and we show that its solutions can be viewed as instanton solutions of a more general system of equations. The latter are the eq…
