Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 6.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$:
\( x^{2} + 18x + 2 \)
Roots:
$r_{ 1 }$ | $=$ | \( 6 a + 11 + \left(15 a + 7\right)\cdot 19 + \left(2 a + 9\right)\cdot 19^{2} + \left(12 a + 17\right)\cdot 19^{3} + \left(8 a + 3\right)\cdot 19^{4} + 5\cdot 19^{5} +O(19^{6})\) |
$r_{ 2 }$ | $=$ | \( 8 + 11\cdot 19 + 4\cdot 19^{2} + 9\cdot 19^{3} + 7\cdot 19^{4} + 3\cdot 19^{5} +O(19^{6})\) |
$r_{ 3 }$ | $=$ | \( 16 + 11\cdot 19 + 6\cdot 19^{2} + 8\cdot 19^{3} + 7\cdot 19^{4} + 18\cdot 19^{5} +O(19^{6})\) |
$r_{ 4 }$ | $=$ | \( 17 a + 14 + \left(10 a + 7\right)\cdot 19 + \left(5 a + 3\right)\cdot 19^{2} + \left(17 a + 1\right)\cdot 19^{4} + \left(18 a + 6\right)\cdot 19^{5} +O(19^{6})\) |
$r_{ 5 }$ | $=$ | \( 2 a + 12 + \left(8 a + 1\right)\cdot 19 + \left(13 a + 17\right)\cdot 19^{2} + \left(18 a + 13\right)\cdot 19^{3} + \left(a + 17\right)\cdot 19^{4} + 7\cdot 19^{5} +O(19^{6})\) |
$r_{ 6 }$ | $=$ | \( 13 a + 17 + \left(3 a + 16\right)\cdot 19 + \left(16 a + 15\right)\cdot 19^{2} + \left(6 a + 7\right)\cdot 19^{3} + 10 a\cdot 19^{4} + \left(18 a + 16\right)\cdot 19^{5} +O(19^{6})\) |
