Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + x - 6 \)
|
The roots of $f$ are computed in an extension of $\Q_{ 5 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 5 }$:
\( x^{2} + 4x + 2 \)
Roots:
| $r_{ 1 }$ | $=$ |
\( 1 + 3\cdot 5 + 5^{2} + 2\cdot 5^{4} +O(5^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 2 a + 2 + \left(3 a + 3\right)\cdot 5 + \left(2 a + 4\right)\cdot 5^{2} + \left(4 a + 2\right)\cdot 5^{3} + 3\cdot 5^{4} +O(5^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 4 + 3\cdot 5 + 4\cdot 5^{2} + 5^{3} + 4\cdot 5^{4} +O(5^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 3 a + 4 + \left(a + 4\right)\cdot 5 + \left(2 a + 3\right)\cdot 5^{2} + 4\cdot 5^{3} + \left(4 a + 4\right)\cdot 5^{4} +O(5^{5})\)
