Eddy diffusivity in convective hydromagnetic systems
M. Baptista, S. M. A. Gama, V. Zheligovsky
An eigenvalue equation, for linear instability modes involving large scales in a convective hydromagnetic system, is derived in the framework of multiscale analysis. We consider a…
Singular-hyperbolic attractors are chaotic
Vitor Araujo, Maria Jose Pacifico, Enrique Pujals +1
We prove that a singular-hyperbolic attractor of a 3-dimensional flow is chaotic, in two strong different senses. Firstly, the flow is expansive: if two points remain close for all…
On the volume of singular-hyperbolic sets
J. F. Alves, V. Araujo, M. J. Pacifico +1
An attractor for a 3-vector field is singular-hyperbolic if all its singularities are hyperbolic and it is partially hyperbolic with volume expanding central direction. We…
