Function

ResidueClassDegree ( elt-pls/fld^fun P ) -> elt-ord^rat

Description

The residue class degree of the place P over its subplace of the rational function field.

Examples

x_gf5 := FiniteField(5); x_gf5t := PolynomialAlgebra(x_gf5); x_gf5tX := PolynomialAlgebra(x_gf5t); x_h := x_gf5tX.1^4+3*x_gf5tX.1^2+x_gf5t.1; x_k := FunctionField(x_h); x_o := MaximalOrderFinite(x_k); x_s := Decomposition(x_o,x_gf5t.1); x_p := Place(x_s[2]); ResidueClassDegree(x_p);
