Mixing-induced activity in open flows

Arthur V. Straube, Arkady Pikovsky

We develop a theory describing how a convectively unstable active field in an open flow is transformed into absolutely unstable by local mixing. Presenting the mixing region as one…

Matryoshka of Special Democratic Forms

Chandrashekar Devchand, Jean Nuyts, Gregor Weingart

Special p-forms are forms which have components ϕ_{μ_1...μ_p} equal to +1,-1 or 0 in some orthonormal basis. A p-form ϕ\in Λ^p R^d is called democratic if the set of nonzero compon…

Multi-Hypersubstitutions and Colored Solid Varieties

Klaus Denecke, Jorg Koppitz, Slavcho Shtrakov

Hypersubstitutions are mappings which map operation symbols to terms. Terms can be visualized by trees. Hypersubstitutions can be extended to mappings defined on sets of trees. The…

Synchronization mechanism of sharp edges in rings of Saturn

D. L. Shepelyansky, A. S. Pikovsky, J. Schmidt +1

We propose a new mechanism which explains the existence of enormously sharp edges in the rings of Saturn. This mechanism is based on the synchronization phenomenon due to which the…

Stellar dynamos with effect

V. V. Pipin, N. Seehafer

We study axisymmetric mean-field dynamo models containing differential rotation, the effect and the additional turbulent induction effects. The additional effects result from t…

The impact of diffusion on confined oscillated bubbly fluid

Sergey Shklyaev, Arthur V. Straube

We consider the dynamics of monodisperse bubbly fluid confined by two plane solid walls and subjected to small-amplitude high-frequency transversal oscillations. The frequency thes…
