Abstract
It is shown that of two conflicting corrections to the dispersion law for spin waves in an antiferromagnetic, Fu-Cho Pu's is rather accurate for short waves, whereas Oguchi's is quite good for long waves. The operator method in terms of spin-flip operators is used in first and second approximation.Keywords
