If I run this code
G.<alpha> = NumberField(x^2-2,latex_name='alpharedefined')
print latex(alpha) #show(alpha)
P.<t> = G[]
H.<beta> = NumberField(t^4-alpha,latex_name='betaredefined')
print latex(beta) #show(beta)
I don't get the latex name of beta redefined. It works for alpha ... Anyone can see where the problem is?
The problem is caused in the first place by a mistake in NumberFieldFactory. In line 610 of sage/rings/number_field/number_field.py(Sage 6.9), the latex_namedoesn't get passed on to the extension method of the base field.
Unfortunately, you cannot get round this by using extension directly; in this case:
sage: G.<alpha> = NumberField(x^2 - 2, latex_name='alpharedefined')
sage: print latex(alpha), G.latex_variable_name()
alpharedefined alpharedefined
sage: P.<t> = G[]
sage: H.<beta> = G.extension(t^4 - alpha, latex_name='betaredefined')
sage: print latex(beta), print H1.latex_variable_name()
\beta betaredefined
The inconsistencies here indicate that there are other things that need correcting in this part of the code.
