For small e, y, (r- 0) is small for all values of a not very near to x. We are

interested, however, in an arbitrary value of u, and in the detailed

boundary layer thus arising. The trick is to consider a limiting procedure where

not only y, ...

While the purely magnetic transition is known [7] (which occurs rigorously when

the masses of two species are equal), one would like to know the

electrostatic potential p(r) generated by the charge separation. Qualitatively, the ...
