Abstract: The paper considers the spectral problem to study of local characteristics of weakly coupled systems in reactor physics. The method of associated invariant subspaces based on the matrix spectrum dichotomy method is described. When using this method, the neutron distributions are found that reflect the multiplicating properties of system local areas.
Keywords: spectrum, invariant subspace, weakly coupled system, fission matrix.
