Lyapunov spectra instability of chaotic dynamo Ricci flows in twisted magnetic flux tubes
Garcia de Andrade
Previously Casetti, Clementi and Pettini [\textbf{Phys.Rev.E \textbf{54},6,(1996)}] have investigated the Lyapunov spectrum of Hamiltonian flows for several Hamiltonian systems by…
Lyapunov spectra in fast dynamo Ricci flows of negative sectional curvature
Garcia de Andrade
Previously Chicone, Latushkin and Montgomery-Smith [\textbf{Comm. Math. Phys. \textbf{173},(1995)}] have investigated the spectrum of the dynamo operator for an ideally conducting…
Geodesic dynamo chaotic flows and non-Anosov maps in twisted magnetic flux tubes
Garcia de Andrade
Recently Tang and Boozer [{\textbf{Phys. Plasmas (2000)}}], have investigated the anisotropies in magnetic field dynamo evolution, from local Lyapunov exponents, giving rise to a m…
Stretch-Twist torus dynamo in compact Riemannian manifolds
Garcia de Andrade
Earlier Arnold, Zeldovich, Ruzmaikin and Sokoloff [\textbf{JETP (1982)}] have computed the eigenvalue of a uniform stretching torus transformation which result on the first Riemann…
Conformal maps in periodic flows and in suppression of stretch-twist and fold on Riemannian manifolds
Garcia de Andrade
Examples of conformal dynamo maps have been presented earlier [Phys Plasmas \textbf{14}(2007)] where fast dynamos in twisted magnetic flux tubes in Riemannian manifolds were obtain…
Plasma torus dynamos versus laminar plasma dynamos
Garcia de Andrade
Earlier Wang et al [Phys Plasmas (2002)] have estimated a growth rate for the magnetic field of and flow ionization velocity of in a laminar plasma slow dyna…
The role of curvature and stretching in dynamo plasmas
Garcia de Andrade
Vishik's antidynamo theorem is applied to non-stretched twisted magnetic flux tube in Riemannian space. Marginal or slow dynamos along curved (folded), torsioned (twisted) and non-…
Acoustic black hole evaporation as plasma diffusion phenomena
Garcia de Andrade
Acoustic analogues of Kerr black hole in plasmas are considered, by taking for granted the existence of acoustic ion waves in plasmas. An effective black holes (BH) in curved Riema…
Kerr-Schild Riemannian acoustic black holes in dynamo plasma laboratory
Garcia de Andrade
Since Alfven, dynamo and sound waves and the existence of general relativistic black holes are well stablished in plasma physics, this provides enough motivation to investigate the…
Exponential stretching in filaments as fast dynamos in Euclidean and Riemannian 3D spaces
Garcia de Andrade
A new antidynamo theorem for non-stretched twisted magnetic flux tube dynamo is obtained. Though Riemannian curvature cannot be neglected since one considers curved magnetic flux t…

Garcia de Andrade
Riemannian and filamentary geometries are used to investigate the stretched filamentary dynamos against solar data in solar corona.
Testing a Riemannian twisted solar loop model from EUV data and magnetic topology
Garcia de Andrade
Compact Riemannian solar twisted magnetic flux tube surfaces model are tested against solar extreme ultraviolet (EUV) lines observations, allowing us to compute the diameter and he…
