  • Approximation of general zero-range potentials 
    Albeverio, S.; Nizhnik, L.P. (Український математичний журнал, 2000)
    A norm resolvent convergence result is proved for approximations of general Schrodinger operators with zero-range potentials. An approximation of the δ’-interaction by nonlocal non-Hermitian potentials (without a renormalization ...
  • Inverse Eigenvalue Problems for Nonlocal Sturm-Liouville Operators 
    Nizhnik, L.P. (2009)
    We solve the inverse spectral problem for a class of Sturm - Liouville operators with singular nonlocal potentials and nonlocal boundary conditions.
