21. Strictly speaking, J i, α c + J i, α s is not an integer due to the staggered factor η i / 3. However, the topological defects are determined from the sum of J i, α c + J i, α s over the four values of the timelike coordinate at fixed space coordinates. The staggered factor drops out from the sum, which is then an even integer.
22. Models based on U (1) × U (1) continuous symmetry, but with different discrete symmetries than discussed here, have been shown to display different critical properties, as discussed, e.g., in Ref..
