Qualitative remarks on some non-linear aspects of the radio-pulsar magnetosphere

In the class of SCLF (space-charge limited flow) submodels of the family of ”gap-plus-PPF” models, let us exposes some qualitative remarks on the possible turbulent dynamics showed by the subzone (II) (see [diagram (♣)] of the text) of the acceleration zone of the ”direct inner gap ”. Furthermore, we will discuss some related physical implications (as, for instance, self-focussing phenomena, Petviashvili’s diamagnetism, etc) concerning structure and physical phenomenology of the remaining subzones (above the subzone (II)) of the given acceleration zone, in connection with possible models for the external solid crust of a radio-pulsar.
