Abstract.
It is not known whether the field of fractions of an integral domain with a compatible lattice order has a compatible lattice order that extends the given order on the integral domain. The polynomial ring \(\mathbb{R}[x,x^{ - 1} ]\) over the real numbers \(\mathbb{R}\) has a natural compatible lattice order, viz, the coordinatewise order ≥. We describe circumstances in which the field of fractions of \((\mathbb{R}[x,x^{ - 1} ], + , \cdot , \geq )\) has no archimedean lattice order that extends ≥.
