Crisis-induced intermittency due to attractor-widening in a buoyancy-driven solar dynamo
Eurico Covas, Mathieu Ossendrijver
In a recent paper [M. A. J. H. Ossendrijver, A&A {\bf 359}, 364 (2000)] numerical simulations of a 2D mean--field model where shown to produce grand minima, typical of the long-ter…

Absence of supersensitivity to small input signals in generalized on--off systems
Eurico Covas, Reza Tavakol
It has recently been shown that nonlinear skew product dynamical systems with invariant subspaces which are capable of displaying on-off intermittency can show supersensitivity to…
