New description:
As pointed out in http://ask.sagemath.org/question/31223, there are
various problems with defining latex_name for the generators of number
fields. For example
{{{
sage: K.<a> = NumberField(x^3 - 5, latex_name='alpha')
sage: latex(a), K.latex_variable_name()
(alpha, 'alpha')
sage: y = polygen(K, 'y')
sage: L.<b> = K.extension(y^3 + a - 1, latex_name='beta')
sage: latex(b), L.latex_variable_name()
(b, 'beta')
sage: M.<c> = NumberField(y^3 + a - 1, latex_name='gamma')
sage: latex(c), M.latex_variable_name()
(c, 'c')
}}}
These, and some other, inconsistencies need ironing out.
