AlffEltInftyVals

Computes the inequivalent valuations of a global function field element at infinity.

Syntax:

L := AlffEltInftyVals(a);

list
  L  
global function field element
  a

Description:

Denote by v_i the s inequivalent normalized valuations extending the degree valuation of k(T) to F. The function returns L:=[v_1(a), … ,v_s(a)] in the tame ramified case.


Example:


kash> AlffInit(FF(5,2));
"Defining global variables: k, w, kT, kTf, kTy, T, y, AlffGlobals"
kash> AlffOrders(y^3+T^4+1);
"Defining global variables: F, o, oi, one"
kash> a := AlffElt(o, [0, 1, 0]);
[ 0, 1, 0 ]
kash> AlffEltInftyVals(a);
> [ -4 ]
