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:
$r_{ 1 }$ | $=$ | \( 16 a + 2 + \left(14 a + 18\right)\cdot 19 + \left(2 a + 18\right)\cdot 19^{2} + 3 a\cdot 19^{3} + \left(14 a + 3\right)\cdot 19^{4} + \left(13 a + 14\right)\cdot 19^{5} +O(19^{6})\) |
$r_{ 2 }$ | $=$ | \( 3 a + 18 + \left(4 a + 16\right)\cdot 19 + \left(16 a + 6\right)\cdot 19^{2} + \left(15 a + 1\right)\cdot 19^{3} + \left(4 a + 14\right)\cdot 19^{4} + \left(5 a + 13\right)\cdot 19^{5} +O(19^{6})\) |
$r_{ 3 }$ | $=$ | \( 16 + 17\cdot 19 + 8\cdot 19^{2} + 18\cdot 19^{3} + 15\cdot 19^{4} + 16\cdot 19^{5} +O(19^{6})\) |
$r_{ 4 }$ | $=$ | \( 12 a + \left(18 a + 8\right)\cdot 19 + \left(17 a + 16\right)\cdot 19^{2} + \left(11 a + 11\right)\cdot 19^{3} + 13 a\cdot 19^{4} + \left(10 a + 9\right)\cdot 19^{5} +O(19^{6})\) |
$r_{ 5 }$ | $=$ | \( 7 a + 12 + 14\cdot 19 + \left(a + 15\right)\cdot 19^{2} + \left(7 a + 5\right)\cdot 19^{3} + \left(5 a + 2\right)\cdot 19^{4} + \left(8 a + 6\right)\cdot 19^{5} +O(19^{6})\) |
$r_{ 6 }$ | $=$ | \( 10 + 9\cdot 19^{2} + 18\cdot 19^{3} + 19^{4} + 16\cdot 19^{5} +O(19^{6})\) |
