Dynamo waves in Friedmann and Misner cosmologies

TL;DR

This paper demonstrates how dynamo wave equations relate to cosmological models, deriving Misner and Friedmann metrics, and explores implications for galactic magnetic fields.

Contribution

It shows that Misner and Friedmann metrics can be derived from dynamo wave equations, linking cosmology with dynamo theory.

Findings

Misner metric corresponds to dynamo wave solutions

Friedmann metrics arise when dynamo waves are absent

Galactic dynamo fields are computed in this framework

Abstract

It is shown that Misner metric can be obtained as solution of dynamo waves equations and Friedmann hyperbolic metrics are obtained when the dynamo waves are absent. In the case of dynamo waves ICM fields are computed and galactic dynamos are obtained.
