| Abstract |
For the beam vibration equation, inverse problems are studied, in which the right-hand
side, i.e., vibration source, is determined. Solutions of the problems using methods of spectral analysis
and the Volterra integral equations are constructed explicitly as sums of series, and the corresponding
uniqueness and existence theorems are proved. In substantiating the existence of a solution to the
inverse problem, in which the right-hand-side factor depending on a spatial coordinate is determined,
the problem of small denominators arises. In relation to this, denominator estimates are found that
guarantee their separation from zero, with an indication of the corresponding asymptotic behavior.
Based on these estimates, the convergence of the series in the class of regular solutions of the beam
vibration equation is substantiated. |
