Asymptotics of the spectrum of the Sturm-Liouville operator with regular boundary conditions


On the interval (0, π), we consider the spectral problem generated by the Sturm-Liouville operator with regular but not strongly regular boundary conditions. For an arbitrary potential q(x) ∈ L 1 (0, π) [q(x) ∈ L 2(0, π)], we establish exact asymptotic formulas for the eigenvalues of this problem.
