| Abstract: | The objective of this paper is to research spectral analysis of transport operator with anisotropic continuous energy homogeneous slab geometry in periodic boundary condition. It proves the transport operator generates a strongly continuous group and the compactness properties of the second-order remained term of the Dyson-Phillips expansion for the C0 group, and to obtain the spectrum of the transport operator only consist of finite isolated eigenvalue which has a finite algebraic multiplicity in trip ?, and to prove the existence of the dominant eigenvalue. |

| Keywords: | transport operator periodic boundary condition C0 group aecond-order remained term dominant eigenvalue |
