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:
| $r_{ 1 }$ |
$=$ |
$ 3 a + 3 + \left(10 a + 9\right)\cdot 11 + \left(2 a + 2\right)\cdot 11^{2} + \left(10 a + 4\right)\cdot 11^{3} + a\cdot 11^{4} +O\left(11^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 2 + 3\cdot 11 + 3\cdot 11^{2} + 9\cdot 11^{3} +O\left(11^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 8 a + 4 + 3\cdot 11 + \left(8 a + 4\right)\cdot 11^{2} + 9\cdot 11^{3} + \left(9 a + 8\right)\cdot 11^{4} +O\left(11^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 4 a + 4 + \left(a + 2\right)\cdot 11 + \left(9 a + 10\right)\cdot 11^{2} + \left(8 a + 2\right)\cdot 11^{3} + \left(a + 1\right)\cdot 11^{4} +O\left(11^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 7 a + 9 + \left(9 a + 3\right)\cdot 11 + \left(a + 1\right)\cdot 11^{2} + \left(2 a + 7\right)\cdot 11^{3} + \left(9 a + 10\right)\cdot 11^{4} +O\left(11^{ 5 }\right)$ |
