Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 163 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 163 }$:
\( x^{2} + 159x + 2 \)
Roots:
$r_{ 1 }$ | $=$ |
\( 46 + 120\cdot 163 + 63\cdot 163^{2} + 62\cdot 163^{3} + 5\cdot 163^{4} +O(163^{5})\)
$r_{ 2 }$ |
$=$ |
\( 100 a + 25 + \left(71 a + 81\right)\cdot 163 + \left(39 a + 131\right)\cdot 163^{2} + \left(2 a + 129\right)\cdot 163^{3} + \left(66 a + 60\right)\cdot 163^{4} +O(163^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 38 a + 23 + \left(162 a + 69\right)\cdot 163 + \left(76 a + 150\right)\cdot 163^{2} + \left(49 a + 65\right)\cdot 163^{3} + \left(132 a + 143\right)\cdot 163^{4} +O(163^{5})\)
