Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 26 a + 30 + \left(23 a + 14\right)\cdot 31 + \left(5 a + 15\right)\cdot 31^{2} + \left(26 a + 5\right)\cdot 31^{3} + \left(8 a + 9\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 5 a + 20 + \left(7 a + 5\right)\cdot 31 + \left(25 a + 3\right)\cdot 31^{2} + \left(4 a + 21\right)\cdot 31^{3} + 22 a\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 29 + 26\cdot 31^{2} + 30\cdot 31^{3} + 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 13 a + 10 + \left(10 a + 19\right)\cdot 31 + \left(14 a + 2\right)\cdot 31^{2} + \left(18 a + 7\right)\cdot 31^{3} + \left(21 a + 24\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 2 + 25\cdot 31 + 24\cdot 31^{2} + 29\cdot 31^{3} + 7\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 6 }$ |
$=$ |
$ 18 a + 5 + \left(20 a + 27\right)\cdot 31 + \left(16 a + 20\right)\cdot 31^{2} + \left(12 a + 29\right)\cdot 31^{3} + \left(9 a + 17\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
