Description (last modified by )
Does not work due to denominators:
sage: K.<a> = NumberField(x^4-4*x^3+12*x^2-16*x+8) sage: L.<u,v> = K.relativize(3*a**3 - 9*a**2 + 24*a -16) # OK sage: L2.<u2,v2> = K.relativize((3/4)*a**3 - (9/4)*a**2 + 6*a -4)
Simpler example:
sage: L.<a,b> = QQ[i].relativize(1) # OK sage: L.<a,b> = QQ[i].relativize(1/2) ... TypeError: Unable to coerce number field defined by non-integral polynomial to PARI.
This is in some sense a duplicate of #252.
