Query: On a Sturm-Liouville Type Problem with Retarded Argument   In this work a Sturm-Liouville type problem with retarded argument which
contains spectral parameter in the boundary conditions and with transmission
conditions at the point of discontinuity are investigated. We obtained
asymptotic formulas for the eigenvalues and eigenfunctions.
