Semiclassical Asymptotics of Solutions to Hartree Type Equations Concentrated on Segments

摘要

We study the nonlinear eigenvalue problem for two-dimensional Hartree type equations with selfaction potentials possessing logarithmic singularity and depending on the distance between points. To find a series of asymptotic eigenvalues, we derive a counterpart of the Bohr-Sommerfeld quantization rule. The corresponding asymptotic eigenfunctions are localized near a plane segment.
