Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} - 5x^{2} + 3x + 4 \) . |
The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: \( x^{2} + 29x + 3 \)
Roots:
$r_{ 1 }$ | $=$ | \( 26 a + 1 + \left(30 a + 1\right)\cdot 31 + \left(5 a + 26\right)\cdot 31^{2} + \left(8 a + 15\right)\cdot 31^{3} + \left(18 a + 26\right)\cdot 31^{4} +O(31^{5})\) |
$r_{ 2 }$ | $=$ | \( 8 a + 12 + \left(25 a + 6\right)\cdot 31 + \left(19 a + 7\right)\cdot 31^{2} + \left(24 a + 26\right)\cdot 31^{3} + \left(5 a + 27\right)\cdot 31^{4} +O(31^{5})\) |
$r_{ 3 }$ | $=$ | \( 5 a + 22 + 5\cdot 31 + \left(25 a + 7\right)\cdot 31^{2} + \left(22 a + 26\right)\cdot 31^{3} + \left(12 a + 23\right)\cdot 31^{4} +O(31^{5})\) |
