I am looking for a computer algebra system that checks if the splitting fields of two polynomials over a $p$-number field are the same or not. At least, knowing their splitting fields are isomorphic will also give me an idea.

In PARI/GP, one can check the Galois of a polynomial upto degree $11$: for example,

P2 = x^9-x+1; polgalois(P2) 

which gives output %3 = [362880, -1, 34, "S9"] , that is, the Galois group is of order $362880$, signature $-1$, and the Galois group is isomorphic to $S_9$.

So given two polynomials up to degree $11$, one can check their Galois group and get some ideas if the splitting fields are equal by looking at their Galois groups.

But how to check the splitting fields/Galois groups of polynomials of degree greater than $11$ over the $p$-adic number field?

I found SageMath computing splitting fields of polynomials of degree more than $11$ over number fields.

However, I am looking for splitting fields or Galois groups over $p$-adic number fields.

Thanks

  • $\begingroup$ I think Magma is pretty good at these things. Beware though that most p-adic numbers do not have a name. $\endgroup$ Commented Sep 14, 2024 at 14:02

  • $\begingroup$ @DaveBenson, can you please tell me what actually it means by "$\text{most $p$-adic numbers do not have a name}$"? $\endgroup$ Commented Sep 15, 2024 at 1:11
  • $\begingroup$ @JorgeZuniga, I didn't use Magma. Can you give a sample code finding Galois group or splitting field of polynomials? $\endgroup$ Commented Sep 15, 2024 at 1:13
