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 $\mathbb{Q}_{ 13 }$:
\( x^{2} + 12x + 2 \)
Roots:
$r_{ 1 }$ | $=$ | \( 1 + 13 + 7\cdot 13^{2} + 8\cdot 13^{3} + 2\cdot 13^{4} + 3\cdot 13^{5} +O(13^{6})\) |
$r_{ 2 }$ | $=$ | \( 6 a + 1 + \left(a + 10\right)\cdot 13 + \left(9 a + 7\right)\cdot 13^{2} + \left(4 a + 1\right)\cdot 13^{3} + \left(9 a + 9\right)\cdot 13^{4} + \left(7 a + 2\right)\cdot 13^{5} +O(13^{6})\) |
$r_{ 3 }$ | $=$ | \( 7 a + 7 + \left(11 a + 5\right)\cdot 13 + \left(3 a + 2\right)\cdot 13^{2} + \left(8 a + 10\right)\cdot 13^{3} + 3 a\cdot 13^{4} + \left(5 a + 1\right)\cdot 13^{5} +O(13^{6})\) |
$r_{ 4 }$ | $=$ | \( 9 a + 8 + \left(a + 9\right)\cdot 13 + 6 a\cdot 13^{2} + \left(7 a + 8\right)\cdot 13^{3} + \left(7 a + 11\right)\cdot 13^{4} + 2 a\cdot 13^{5} +O(13^{6})\) |
$r_{ 5 }$ | $=$ | \( 5 + 10\cdot 13 + 2\cdot 13^{2} + 13^{3} + 3\cdot 13^{4} + 9\cdot 13^{5} +O(13^{6})\) |
$r_{ 6 }$ | $=$ | \( 4 a + 4 + \left(11 a + 2\right)\cdot 13 + \left(6 a + 5\right)\cdot 13^{2} + \left(5 a + 9\right)\cdot 13^{3} + \left(5 a + 11\right)\cdot 13^{4} + \left(10 a + 8\right)\cdot 13^{5} +O(13^{6})\) |
