Norkin, Differential equations of the second order with retarded argument, Translations of Mathematical Monographs, Vol. 31, AMS, Providence, RI, 1972] and suggesting own approaches we find asymptotic formulas for the eigenvalues and eigenfunctions of boundary value problems of Sturm-Liouville type for the second order differential equation with retarded argument.en10.1501/Commua1_0000000810info:eu-repo/semantics/openAccessDifferential equation with retarded argumenttransmission conditionsasymptotics of eigenvalues and eigenfunctionsSturm-Liouville ProblemsTransmission ConditionsEigenfunctionsEigenvaluesArticle662175194N/AWOS:000407117100015
