| 1 | 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 |

| 2 | {{{ |

| 3 | sage: K.<a> = NumberField(x^3 - 5, latex_name='alpha') |

| 4 | sage: latex(a), K.latex_variable_name() |

| 5 | (alpha, 'alpha') |

| 6 | sage: y = polygen(K, 'y') |

| 7 | sage: L.<b> = K.extension(y^3 + a - 1, latex_name='beta') |

| 8 | sage: latex(b), L.latex_variable_name() |

| 9 | (b, 'beta') |

| 10 | sage: M.<c> = NumberField(y^3 + a - 1, latex_name='gamma') |

| 11 | sage: latex(c), M.latex_variable_name() |

| 12 | (c, 'c') |

| 13 | }}} |

| 14 | |

| 15 | Also |

| 16 | {{{ |

| 17 | sage: E.<rho> = NumberField(x^3 - 5) |

| 18 | sage: latex(rho), E.latex_variable_name() |

| 19 | (\rho, '\\rho') |

| 20 | sage: F.<rho> = NumberField(x^3 - 5, latex_name='rho') |

| 21 | sage: latex(rho), F.latex_variable_name() |

| 22 | (rho, 'rho') |

| 23 | sage: G.<rho> = NumberField(x^3 - 5, latex_name='sigma') |

| 24 | sage: latex(rho), G.latex_variable_name() |

| 25 | (sigma, 'sigma') |

| 26 | }}} |

| 27 | All these inconsistencies need ironing out. |
