1766	 Quasilinearization and the Estimation of Differential Operators from Eigenvalues	 Given a linear ordinary differential operator containing several unknown constants and a number of its eigenvalues the values of the unknown constants are estimated. A precise formulation is provided and an effective numerical procedure for solution is indicated. The results of some computational experiments are given. quasilinearization eigenvalues differential operators nonlinear boundary-value problems inverse problems differential equations system identification
