Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 17 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 17 }$: $ x^{2} + 16 x + 3 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 15 a + 8 + \left(3 a + 16\right)\cdot 17 + \left(13 a + 15\right)\cdot 17^{2} + \left(12 a + 10\right)\cdot 17^{3} + \left(4 a + 3\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 8 + 13\cdot 17 + 14\cdot 17^{2} + 16\cdot 17^{3} + 7\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 2 a + 6 + \left(13 a + 5\right)\cdot 17 + \left(3 a + 8\right)\cdot 17^{2} + \left(4 a + 10\right)\cdot 17^{3} + \left(12 a + 12\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 13 a + 9 + \left(12 a + 16\right)\cdot 17 + \left(11 a + 14\right)\cdot 17^{2} + \left(4 a + 9\right)\cdot 17^{3} + \left(a + 6\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 4 a + 5 + \left(4 a + 16\right)\cdot 17 + \left(5 a + 13\right)\cdot 17^{2} + \left(12 a + 2\right)\cdot 17^{3} + \left(15 a + 3\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
