摘要
The Lax representation for the continuous Heisenberg spin chain equation is given by L. A. Takhtajan(Phys. Lett., 64A(1977), 235), the higher-order Heisenberg equations are obtained by D. Y. Chen and Y.S. Li(Acta Math. Sinica, 2(1986), 343). In this letter, we first give the commutator representation of the higher-order Heisenberg vector field,
