板模型中一类带广义边界条件具各向异性迁移算子A的谱
The Spectrum of Transport Operator with General Boundary Condition in Slab Geometry
【摘要】 研究在板模型中一类带广义边界条件具各向异性、单能、均匀介质迁移算子A的谱,证明了其生成的C0半群为不可约半群及迁移算子A的一些谱性质。
【Abstract】 The paper is concerned with the spectral properties of the transport operator with general boundary conditions.First we prove the transport operator generates a strongly continuous group,second we discuss the irreducible of the transport semigroup,in the last we obstain the spectral struction of the transport operator.
