Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 13 }$ to precision 6.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 13 }$: $ x^{2} + 12 x + 2 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ a + 3 + \left(3 a + 3\right)\cdot 13 + \left(6 a + 2\right)\cdot 13^{2} + \left(11 a + 9\right)\cdot 13^{3} + \left(a + 3\right)\cdot 13^{4} + \left(5 a + 8\right)\cdot 13^{5} +O\left(13^{ 6 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 4 a + 10 + \left(10 a + 12\right)\cdot 13 + \left(12 a + 12\right)\cdot 13^{2} + \left(11 a + 9\right)\cdot 13^{3} + \left(10 a + 3\right)\cdot 13^{4} + \left(7 a + 7\right)\cdot 13^{5} +O\left(13^{ 6 }\right)$ |
