| Abstract: | In this paper,a class of integro-differential operators,which arises in transport theory is discussed.By using linear operator theory in L 2 space,the representation of the essential spectrum of the operators of this kind is obtained.We also got a condition of the existence of dominant eigenvalues to the operators. |
