First, we investigate the simplicity of eigenvalues and then prove the existence theorem. As a result, we obtain the asymptotic formulas for eigenvalues and eigenfunctions.en10.1007/s11253-017-1292-zinfo:eu-repo/semantics/openAccessEigenvalue ParameterEigenfunctionsArticle68812631277Q4WOS:000394352000009
