摘要: Abstract Two exactly solvable models illustrating the links between spectral properties of Hamiltonians, connections on induced Hilbert bundles and topological characteristics basis spaces are considered. The first them is based extension theory for symmetric operators second one-dimensional Laplace operator with parametrical boundary conditions.
