AlffOrderEqFinite

Computes an equation order of the given algebraic function field.

Syntax:

o := AlffOrderEqFinite(F);

algebraic function field order
  o  
algebraic function field
  F  

See also:  AlffOrderEqInfty, Alff, AlffElt

Description:

Computes the k[T]-equation order of an algebraic function field F/k(T), that is k[T, rho] where f(T, rho) = 0 and F/k(T) is defined by f.


Example:


kash> AlffInit(FF(5,2));
"Defining global variables: k, w, kT, kTf, kTy, T, y, AlffGlobals"
kash> F := Alff(y^3+T^4+1);
Algebraic function field defined by
.1^3 + .2^4 + 1
over
Univariate rational function field over GF(5^2)
Variables: T
