Stretching magnetic fields by dynamo plasmas in Riemannian knotted tubes

Garcia de Andrade

Recently Shukurov et al [Phys Rev E 72, 025302 (2008)], made use of non-orthogonal curvilinear coordinate system on a dynamo Moebius strip flow, to investigate the effect of stretc…

Spectrum of kinematic fast dynamo operator in Ricci flows

Garcia de Andrade

Spectrum of kinematic fast dynamo operators in Ricci compressible flows in Einstein 2-manifolds is investigated. A similar expression, to the one obtained by Chicone, Latushkin and…

Ricci dynamo stretch-shear plasma flows and magnetic energy bounds

Garcia de Andrade

Geometrical tools, used in Einstein's general relativity (GR), are applied to dynamo theory, in order to obtain fast dynamo action bounds to magnetic energy, from Killing symmetrie…

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…

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-…

Stretch fast dynamo mechanism via conformal mapping in Riemannian manifolds

Garcia de Andrade

Two new analytical solutions of self-induction equation, in Riemannian manifolds are presented. The first represents a twisted magnetic flux tube or flux rope in plasma astrophysic…

Plasma planar filament instability and Alfven waves

Garcia de Andrade

Inhomogeneous plasmas filaments instabilities are investigated by using the techniques of classical differential geometry of curves where Frenet torsion and curvature describe comp…
