Stability of a heteroclinic network and its cycles: a case study from Boussinesq convection

Olga Podvigina, Sofia B. S. D. Castro, Isabel S. Labouriau

This article is concerned with three heteroclinic cycles forming a heteroclinic network in $R^{6}$ . The stability of the cycles and of the network are studied. The cycles a…

Negative magnetic eddy diffusivity due to oscillogenic $α$ -effect

Alexander Andrievsky, Roman Chertovskih, Vladislav Zheligovsky

We study large-scale kinematic dynamo action of steady mirror-antisymmetric flows of incompressible fluid, that involve small spatial scales only, by asymptotic methods of the mult…

An example of non-uniqueness for the weighted Radon transforms along hyperplanes in multidimensions

F Goncharov, R Novikov

We consider the weighted Radon transforms $R_{W}$ along hyperplanes in $R^{d}, d \geq 3$ , with strictly positive weights $W = W (x, θ), x \in R^{d}, θ \in S^{d - 1}$ . We construct…

Magnetic field generation by pointwise zero-helicity three-dimensional steady flow of incompressible electrically conducting fluid

A. Rasskazov, R. Chertovskih, V. Zheligovsky

We introduce six families of three-dimensional space-periodic steady solenoidal flows, whose kinetic helicity density is zero at any point. Four families are analytically defined.…

Pseudo-simple heteroclinic cycles in $R^{4}$

Pascal Chossat, Alexander Lohse, Olga Podvigina

We study pseudo-simple heteroclinic cycles for a $Γ$ -equivariant system in $R^{4}$ with finite $Γ \subset O (4)$ , and their nearby dynamics. In particular, in a first step towards a fu…
