The positivity principle in Boltzmann‐type equations

摘要

AbstractClassical theorems about matrices with non‐negative elements can be generalized for application in eigenvalue problems of integro‐differential form appearing in the description of stationary particle transport. In this way the existence and unicity of positive L1‐eigensolutions of them‐quasi‐completely‐continuous transport operator can be deduced. These solutions can be realized by a method of successive ap
