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