THE RELATIVISTIC ROTATION TRANSFORMATION AND PULSAR ELECTRODYNAMICS

The substitution of the relativistic rotation transformation (RRT) of Trocheris and Takeno to the Galilean type one, establishing a nonlinea r relation between speed v and angular velocity omega [v = c tanh (ome gar/c)], not only sends to infinity the ''light cylinder'' and modifie s the characteristic parameters of pulsars within the corotating sourc e model (Kichenassamy & Krikorian 1991), but also circumvents the chan ge of type of the differential equations for the electromagnetic poten tial when a quasi-static constraint is assumed; on the other hand, the resulting equations for a force-free magnetosphere reduce to those of Mestel, at the nonrelativistic approximation, when RRT reduces to the usual ''instantaneous Lorentz transformation;'' indeed, difficulties related to energy flow across the light cylinder become ipso facto mea ningless.
