We analyze the characteristic equation of the boundary value problem for eigenvalues and de-rive asymptotic expansions of arbitrary order. We apply the obtained results to the problem with two-point nonlocal boundary condition.en10.3846/mma.2023.17617info:eu-repo/semantics/openAccessSturm-Liouville problemDirichlet conditiontwo-point nonlocal conditionsasymptotics of eigenvalues and eigenfunctionsEigenvalue ParameterSpectrum CurvesEigenfunctionsArticle282308329Q1WOS:0009570756000082-s2.0-85151464374Q3
