| Abstract: | Using the Fermi coherent state and the integration technique of normal-ordered to study exchange operators of the two states in a Fermi system,we obtain the operators in the coherent state representation and the number representation.Furthermore,we generalize the results to the case of several states. |

| Keywords: | Fermi operator coherent state anti-commutative c-number |
