In this talk we will present a series of results and open problems emerging from the study of infinite global fields. We will give a survey of the asymptotic properties of the Brauer-Siegel and Euler-Kronecker invariants in the classical situation of number fields and function fields as well as in certain higher dimensional cases. ...

... The are two main sources of magnetospheric electric fields. The other is the solar wind related, dawn-to-dusk directed ("convection") field, and the other is the co-rotation electric field related to the rotation of the Earth along its spin axis. The electric fields have a strong effect on the drift paths of the magnetospheric plasma . ...
