Resumen:
In this work, the quadratic helicity χ(2)is discussed from the physical and topologicalpoints of view. We show, after the introduction of a mathematical description of theproperties of helicity and quadratic helicity in the context of standard dynamo equations,examples of the importance of these high invariants in cosmological scenarios. Thesescenarios consider extensions of the standard model and extensions of GR.
